92 buick lesabre 3800 runs rich

Question From autotechnoob on 92 buick lesabre 3800 runs rich

ok so i have a 92 buick lesabre 3800 with tuned port injection it has a rough idol, i know for a fact its running rich because i have hooked it up to a scan tool and it ran lean/rich back and forth for about 5 min then went straight rich with no codes. i know its not the o2 sensor(its been replaced) fuel pressure reads 40.7. vacuum pressure is fine and dandy between 17 to 18 hg. and to add ive checked injectors with a beep tester from snap-on and all injectors are firing. have also replaced maf sensor car is sluggish at acceleration is now jerking slightly on me now when going highway speed. so i need help asap running out of ideas and it my only mode of transportation. the only thing i can think of is it might be the iac valve any suggestions?

Response From Hammer Time

If it's not setting any rich codes, what makes you think it's running rich? I seriously doubt it.

Response From autotechnoob

well the scan tool i used had lights for the rich/lean they blinked back and fourth and then it just stayed lit on rich but displayed no codes

Response From Hammer Time

I doubt it's really running rich. It will set a code as soon as the adaptives can no longer compensate for it. It was probably just the scan tool being unable to update the data fast enough.

Response From autotechnoob Top Rated Answer

well if that is the case what else would make my cat burn up because it was just replaced and i had to take it out cause the honey comb got burnt up again and it was gettin clogged? could a cloged up muffler do that?

Response From Hammer Time

That makes no sense at all. Why would you gut out a new cat that was still under warranty?
Your car is not running rich. The ecm would set a code when it reached adaptive limits.

Response From autotechnoob

ok well it wasnt under warranty cause i put it in myself and like i said its my only mode of transportation and i live out in the middle of the country so it would really suck to have my car break down on me in the middle of nowhere and i barley got home the night i took it out and it was burnt up and i didnt gut it i just put straight pipe in till i could get the problem fixed because i do go to college for automotive technology so im kinda broke cant afford to buy a new one quite yet and my teachers wont help unless its ford product for some reason. so now im out of ideas which is why im resulting to fourms. and its not just that scan tool either ive used a few (snap on, an actual gm obd1, my cheap one from napa) and none come up with codes so if you have any other possible ideas im all open ears.

Response From Hammer Time

I don't know what it is that your trying to fix. Even if it was running rich, that wouldn't take out the cat. Raw fuel, heavy oil consumption or coolant are the things that plug up converters. It would have to be blowing black smoke for a very long time to take out the cat. Other than your idea that it's running rich, I haven't read any other issues or symptoms.

Response From autotechnoob

well it has been using large ammounts of fuel after i started having problems with it i was getting 340 -360 miles to the tank now i get about 200 if im lucky and its all highway. and my oil gradually has been getting lost so idk every one seems to not know so im just looking for anything that might help send me in the right direction and im stubborn i wont let some one else work on my vehicle plus if im going to make it in this field i need to figure it out

Response From Hammer Time

Your going to have to examine the sensor data more closely. If you have the ability for customer data, delete everything but O/2 readings, Integrator and block learn and injector pulse width.
You need to look for a pattern where the o/2s go rich. When you see that look to see what the injector pulse width does along with the block learn. On block learn, 123 is center, anything lower is leaner and anything higher is richer. See what they are doing to be avblle to determine what really is happening here. You could have a bad ECM that is going rich and doesn't know it.

Response From autotechnoob

ok come monday ill be able to get ahold of a scan tool again and thank you for your help ill repost when i find something but if it is the pcm im gonna be pissed cause its been replaced twice and im gonna have to raise hell with some people

Response From Hammer Time

If things start pointing toward an ECM, then you'll have to start checking all the grounds for the ECM. I have seen a bad ECM ground act like that. Get a pinout diagram and verify all the grounds but only if these tests start pointing to a bad ECM.

Response From autotechnoob

also if it isnt hard enough to tell no black smoke

buick stalling

Question From revdesigns on buick stalling

I have a 1995 buick lesabre custom, v6 fuel injected. Here's the ?, awhile back it started sputturing going up big hills, or giving it gas pulling away from a traffic light. Then would stall randomly, seems like it would only stall when i wasn't on the gas. It has a fairly rough idle, here's what i've replaced so far...

Fuel Filter
fuel pump
spark plugs
wires
checked ignition module, works fine
checked to make sure all were firing
correct gaps in plugs
ran fuel injector clearner through it
recent oil change
check engine light isnt on
no funny noises

i dont have access to a scanner, and i'm stumped. :(

Any help is very much appreciated, thanks for your time.

Response From leonard Top Rated Answer

Check your cat. converter, sounds like it's plugged. Make sure you also check the muffler, somtimes the baffles will collapse inside and your car cant exhaust like it should, also, if that's a db1 system, you dont need a scanner to check for trouble codes, you can access the adl link with a "computer key" or a paper clip but if theres no codes or the light isnt on, then theres no need.
Leonard

Response From bryan_kilco

I'm having this exact same problem. The problem did semm to come back when my exhaust leak got a bit worse.....just trying to pinpoint exactly what I should do, and if I should take it somewhere or do it myself.

Response From bryan_kilco

bah! i need some help!

aside from the stalling issue, my tranny will slip once the car gets warm, and today it was slipping bad and it has fluid......the speedometer drops to 0 and she loses power. anyone know what this could be?

Response From DanD

There are so many could be’s that without getting under the hood and checking things first hand, anything I suggest may take you on a wild goose chase?
ran fuel injector clearner through it

If you mean you poured something into the tank that usually won’t help you if there is an actual plugged or dirty injector. Those cleaners are not aggressive enough to do much of anything; they have their place as a preventative maintenance item but not when there’s a dirt problem. Maybe try having the system professionally cleaned and then an injector balance test performed.
The injectors may not even be dirty but one mite be beginning to fail electrically?

Question From terasys on 2001 Buick Cat/o2 sensor contamination P0420

Well. My car:

2001 Buick LeSabre Custom 3.8 160k miles

has the infamous p0420 code. I have noticed decreased fuel efficiency (on average the last week its around 12 mpg.... yeah..)

I know the code points to the Cat not working efficiently or as it should, but I wanted to test the upstream o2 sensor first because that could explain the bad gas mileage.

It passed inspection last year only because the mechanic cleared the code and then let it slide. I decided to test the upstream o2 sensor first before shelling out 100's.

It seemed to be working fine: went up to 0.9 volts under high temps and went back down to under 0.1 volts very quickly in around 1-2 seconds. Seems pretty normal. BUT, the head of the o2 sensor was chalky white. Which is a tell tale sign of silicone contamination. I suppose this could lead to my cat being inefficient and thusly throwing the code.

The problem is: I read online that coolant has silicone in it. Last year I got a coolant flush and got it filled up. Since then, my coolant reservoir has gone from about 1/3-1/2 full to pretty much empty right now. Does it usually just go away like that? Could it be leaking into the engine somehow? Could this be put on the mechanic's (Sears..psh) fault? Did they mess it up somehow and make a leak?

I also have a pretty good (bad) power steering leak. I need to put a new bottle in about every 2 weeks or so. I ALSO have a slight oil leak too. The guy who owned the car before me said it just burns up as it drips off. I need to add a quart of oil every 3-4 months MAYBE. I haven't since probably last summer and it needed 2 quarts when I recently did add some.

The bottom of my car has a pretty decent layer of black tar/oil coating everything. including almost all of the hoses near the front axle. My car will leak (which I believe is power steering fluid) 100% of the time. No matter if I let it sit for an hour or 2 seconds. it is constantly dripping.

Any ideas?

Should I test the downstream o2 sensor? (pain in the ass)

Thanks!

Response From Hammer Time

Some of what you are saying has a little truth and most of it is out in left field.

Coolant doesn't contain silicone, some of it contains silicates but not Dexcool which is what you should have in there.

You have a bad Cat. The PO420 rarely indicates anything but a bad Cat because of the criteria it takes to set that code. The white on the 0/2 sensor doesn't mean anything bad and that's pretty normal. You're way off on how the 0/2 is supposed to operate also. I don't know where your coolant is going but you should be able to find out with some careful pressure testing. That particular engine has a known problem with intake manifold deterioration causing coolant to leak into a vacuum chamber under it. There is a TSB on that.

Response From terasys

Link deleted.................. is where I found the information about the o2 sensors colors.

I wanted to save so money so what I was going to do was buy a cat online (they run from (what i saw) around 90-300) and I know a mechanic who will install one for about 75 bucks.

will that clear the code? Should I get him to install new o2 sensors as well? Or should I just buy a new upstream? Because honestly I went through 4 gallons (16 dollars) of gas going about 45 miles.

What is a TSB? Can you link this?

Response From Hammer Time

We don't allow links on the site but I will post an image of the TSB. They don't list your year but it's still possible. As I said, you need to pressure test.

I wouldn't even attempt to buy a converter online. Just go to a custom exhaust shop and they will install one for likely less money that you can even buy one. My shop gets $180 installed for a universal cat.

As far as the 0/2s, don't be too concerned with the color as much as how they operate. Sensor will deteriorate over time so changing them is never a bad idea. The upstream is the only one that has anything to do with fuel mixture. The downstream is a Cat monitor only.



Response From terasys

Okay awesome.

I figured it would be like 400-600 for something like that.

I will call a couple places and see what the prices look like.

Thanks for that pic but where do I find more information? Just googling?

And: I read many reviews online that a new cat sometimes does not clear the code. Any reason why it wouldn't in my case? (Your best guess obviously).
Thanks again!

Response From Hammer Time

I have seen that code dozens of times and only once did a new Cat not resolve it and in that case, the exhaust pipe had a crack in it just ahead of the cat and the oxygen was confusing the sensors.

Response From terasys

How long will it take to have the code come back on after clearing it? Its been over 25 miles since I cleared it and it has not come back yet..

Response From Hammer Time

It takes a while because the computer has to see very specific criteria and it may have to see it more than once.

Here's some reading for you on that code



CIRCUIT DESCRIPTION
In order to control emissions of Hydrocarbons (HC) , Carbon Monoxide (CO) , and Oxides Of Nitrogen (NOx) , a three-way catalytic converter is used. The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas, converting them into harmless water vapor and carbon dioxide. The catalyst also reduces NOx, converting it to nitrogen. The converter also has the ability to store excess oxygen and release the stored oxygen to promote these reactions. This Oxygen Storage Capacity (OSC) is a measurement of the catalyst's ability to control emissions. The Powertrain Control Module (PCM) monitors this process using a Heated Oxygen Sensor (HO2S) located in the exhaust stream past the 3-way converter. When the catalyst is functioning properly, the HO2S 2 is slow to respond to a large change in the HO2S 1 signal. When the HO2S 2 responds quickly to a large change in the HO2S 1 signal, the OSC and efficiency of the catalyst is considered to be bad and the MIL will be illuminated if subsequent tests also indicate a failure.

CONDITIONS FOR RUNNING THE DTC

  • Meet he conditions for engine warm up. Use the scan tool catalyst data list in order to verify the following.
  • DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0130, P0131, P0132, P0133, P0134, P0135, P0137, P0138, P0140, P0141, P0171, P0172, P0201-206, P0300, P0336, P0341, P0401, P0403, P0404, P0405, P0410, P0412, P0418, P0440, P0442, P0443, P0446, P0449, P0502, P0503, P0506, P0507, P1133, P1134, P1336, P1351, P1352, P1361, P1374, or P1441 are not set.
  • The engine has been running more than 10 minutes.
  • The Engine Coolant Temperature (ECT) is above 70°C(158°F) and below 124°C (255°F).
  • The Barometric Pressure (BARO) is above 75 kPa.
  • The vehicle is in Closed Loop.
  • The Intake Air Temperature (IAT) is above - 20°C (-4°F) and less than 100°C (212°F).
  • The battery voltage above 10.7 volts
  • Warm up the catalyst.
  • Fully open the hood.
  • Place the transmission in park (automatic) or neutral (manual).
  • Set the parking brake.
  • Press and hold the service brake.
  • Each time the engine is started, the diagnostic can run up to 18 times. After the 10-minute run time and before the diagnostic runs the first time, the engine must run an additional 5 minutes between 1500-2500 RPM.

  • For any additional tests on the same key cycle, the engine speed must be between 1500-2500 RPM for 1 minute.
  • In order to activate the diagnostic return the vehicle to idle and put the vehicle in drive, or depress the clutch for a manual transmission.
  • Test the catalyst.
  • Place the transmission in drive (automatic) or neutral (for manuals with clutch depress).
  • VIN K California Emissions- Within 60 seconds the air fuel ratio will go rich below 14.1 for up to 6 seconds , then it may go lean above 15.3 for up to 8 seconds.
  • VIN K FED Emissions-Within 60 seconds the air fuel ratio will go lean above 15.3 for up to 6 seconds , then may go rich below 14.1 for up to 7 seconds.
  • VIN 1-With in 60 seconds the air fuel ratio will go rich below 14.1 for up to 7 seconds , then it may go lean above 15.3 for up to 9 seconds.
  • Check if DTC P0420 has passed or failed this key cycle using the scan tool.

  • CONDITIONS FOR SETTING THE DTC
    The PCM determines that the catalyst's oxygen storage capacity is below an acceptable threshold.

    ACTION TAKEN WHEN THE DTC SETS
  • The control module illuminates the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails.
  • The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

  • CONDITIONS FOR CLEARING THE MIL/DTC
  • The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
  • A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
  • A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
  • Use a scan tool in order to clear the MIL and the DTC.

  • DIAGNOSTIC AIDS
    Check for the following conditions:
  • The PCM will not enable the catalyst test until following conditions are met:
  • The engine speed is plus or minus 100 RPM from the desired idle.
  • The Throttle Position (TP) is 0.0 percent.
  • The short term integrator is between -20 percent and +20 percent.
  • The catalyst test will abort if the vehicle falls outside the conditions listed below while the test is running:
  • The engine speed is plus or minus 125 RPM from desired idle.
  • The Throttle Position (TP) is 0.0 percent.
  • Short term integrator is between -20 percent and +20 percent.
  • The catalyst test may abort due to a change in engine load, for example, from the A/C or from the coolant fan. If this condition occurs, use the scan tool in order to force the cooling fans ON, and return to Step 2 in the table.

  • IMPORTANT: When using the scan tool to force the cooling fans on use the next list and previous list soft keys to enter the catalyst data list. If the catalyst data list is not entered this way the cooling fan control will be canceled.

  • More than 6 tests may have to be attempted in order to get 6 completed tests. An aborted test counts as an attempted test. The number of attempt tests is limited to 18 per key cycle.

  • After returning to an idle the HO2S 1 signal may stay rich or lean for several seconds causing the test to be delayed.
  • A faulty connection at PCM-Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection. Use a corresponding mating terminal to test for correct terminal tension.
  • A damaged harness-Inspect the wiring harness for damage. If the harness appears to be OK, observe the display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the display will indicate the location of the fault.

    Oh.. I see.

    It came on tonight actually. After driving a total of 30 miles. but I didn't know it had to be specific criteria like that.

    Thanks anyway. I got an appointment on 5/30 as supposedly the best auto place in the area. His appointments can take up to 2 weeks because so many people go to his place. Supposedly he also does not charge much.

    Hopefully it works out okay

    Response From Hammer Time

    You're not looking for the best repair shop in town. You're looking for an exhaust specialty shop. General repair shops are not equipped for custom exhaust and will be more expensive.

    Response From terasys Top Rated Answer

    The closest thing to an exhaust shop near me is Monro.

    Are they okay?

    I believe I have heard mixed things about them.

    Edit: On their website they are offering a 30% off muffler/catalytic converter sale.

    Will that be pretty cheap? I will call tomorrow.

    Thanks again

    Response From Hammer Time

    It doesn't matter who they are as long as they have a pipe bender on-site. That would mean that they are in the business of making custom exhaust and have the toola and ability to do what's needed at a reasonable price. If they do not make custom exhaust on a regular basis, they cannot be competitive with the price. Midas may be the exception to that. They are always kinda expensive.

    Response From terasys

    Well.. I called one Monro and they said they cannot give me an estimate so I made an appointment on Tuesday morning for them to check it out.

    So I called another Monro and he calculated the cost to be 465 for a universal and 700 for an OEM.

    yeah.... I will keep looking. That is ridiculous

    Edit: Should I be looking for custom exhaust shops?

    Edit: Should I be looking for custom exhaust shops?

    Didn't I say that 3 times?

    Response From terasys

    You said "exhaust specialty" shops.

    I have no idea if that is the same as custom? How does custom which includes like stainless steel compare to just having exhaust as a specialty? I guess it is clearer to trained eyes..

    Response From Hammer Time

    OH, come on............


    Exhaust specialty...................... to mean specialize in exhaust repair.



    Maybe you recall reading this....

    Just go to a custom exhaust shop and they will install one for likely less money that you can even buy one. My shop gets $180 installed for a universal cat.

    Response From terasys

    Hahaha Okay okay okay. I got it. I got a couple places lined up.

    Response From Tom Greenleaf

    I have no specific problem with any chain. If they are having a sale go for it. Best will always be OE stuff for exhaust items IMO but if it works and a bargain can't argue,

    (sorry for spammer being removed now)

    Response From terasys

    Well the thing is i Have multiple issues. I want all the leaks fixed as well. I have an appointment on the 30th to get it checked out. If getting a new cat installed is around 200-250 ill get it done. If i can find a better place in the area, ill do it there.

    I havent seemed to find a custom exhaust place.
