MAF Sensor Probems

Question From KerokeroCola on MAF Sensor Probems

Year of vehicle - 1998
Make of vehicle - Isuzu
Model of vehicle - Rodeo
Engine size - 3.2L V6
Mileage/Kilometers - 162k

I am having issues with my SUV's Mass Airflow Sensor. The "Check Engine Light" has been on for some time now. Additionally, I find that it idles low and is lurchy when I take my foot off the accelerator--indicating to me that the engine is running too rich.

I brought it in for a diagnosis, and I was told it was a problem with the MAF Sensor. I first tried cleaning it using some MAF Sensor Cleaner; no good. The Check Engine light and the symptoms persisted. So I completely replaced the MAF Sensor (and the air filter for good measure) with no avail. I refunded the part because it was potentially damaged; the new part still doesn't work. Additionally, I've very closely examined the rubber coupler between the MAF Sensor and the air filter box to see if there is any leakage; there is not. As far as I can tell, the whole air intake system on my car is in fine shape.

I hate to think it's the dreaded "e-word," (electrical) but I'm starting to think this is a problem with my car's computer reading the MAF Sensor wrongly. What can I do?

Response From Mr.scotty

I agree with re-tired.
If everything electrical checks out, I would be looking into the intake gasket.
Do you plan on doing this your self or letting someone else do it?
And can you post the code number that you got when it was scanned?

Response From Mr.scotty Top Rated Answer

It would be a good idea to have the vehicle hooked up to a good scanner so you can see what the PCM is reading from the MAF sensor (if anything at all).
Could be as simple a broken wire or a bad connector.

Don't keep throwing parts at it though, you won't get any where doing that.

Response From re-tired

I did a google search on your yr/make/model . There are a lot of complaints similar to yours that are being solved with replacment of intake gasket.

Question From fokes123 on 1993 ford ranger question please help !!!

I have a 1993 ford ranger 2.3 and i am wondering if i can fit the k&n 57 Series FIPK cold air intake. The oldest year they have is 1995 ranger 2.3 and i am wondering if it would fit my 93 ranger. Also just to make sure with this k&n cold air intake, it would pass smog and be street legal? Thanks!

Response From Hammer Time

Yep, that cold air intake is just a waste of money.

Response From Discretesignals

Save yourself some money and make your own custom cold air intake.


Response From Hammer Time

I don't know how they call these things COLD air intakes when they pull in the superheated air from under the hood. Just a way to take your money.

Response From Tom Greenleaf

OK - went a bit nuts but it's a serious misleading as bad as any Sham-Wow infomercial.
People: Gas/fuel doesn't like COLD air dag nabbit! If too cold it would never atomize (evaporate) to be able to work in time. All sorts of efforts are to warm air not cool it up to putting strong electric heaters under throttle body or carbs then AND run total exhaust heat as well so evaporating fuel (gets cold just doing that like sweat on your skin) can even ice up so it's making itself cold anyway and has to be corrected or you'd just flood out.


No clue how these scams get out there and not pulled from the market place instantly?


True: Cold air has more density (heavier) than warm air - Google out what a hot air balloon is lifted by


The end all is if any of these tricks worked at all or had any benefit it would be designed into the engines to begin with.


This and a ton of bullcrap sells so they keep making it. If it floats your boat go for it but don't complain when it's all worse than before you messed with it,

Thanks for all the help guys..... Dont really need your guys opinions on them i really didnt ask. You guys seemed to think i did but you all maged not to answer my question and insted just go on a rant about them. This was a waste of time IMO.....looks like I'll have to take this to a better forum.

Response From Hammer Time

No problem, We won't miss you.

Response From fokes123

Its funny because on your quote it says that you help answer questions but you didnt do jack shit and managed just to bag on me. Nice way to welcome new member on the forum. This is extremely dissapointing

Response From Discretesignals Top Rated Answer

Good information Tom. Like they say, K&N filters are really only good for filtering out rocks...lol. GM came out with a TSB a while back concerning those filters and how they were causing MAF issues. GM stated they wouldn't honor damage done by using those filters. K and N went bananas over that one.

Automatic Transmission Shift, Engine Driveability Concerns or Service Engine Soon (SES)
Light On as a Result of the Installation of an Aftermarket Reusable, Excessively Oiled Air Filter

Models: 2004 and All Prior Cars and Light Duty Trucks
2003-2004 HUMMER H2

DO THIS
First, Inspect the vehicle for a reusable aftermarket excessively oiled air filter

DON'T DO THIS
DO NOT repair under warranty if concerns result from the use of a reusable aftermarket oiled air filter.

The installation of an aftermarket reusable, oiled air filter may result in:

1. Service Engine Soon (SES) Light On

2. Transmission shift concerns, slipping and damaged clutch(es) or band(s)

3. Engine driveability concerns, poor acceleration from a stop, limited engine RPM range

The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.

When servicing a vehicle with any of these concerns, be sure to check for the presence of an aftermarket reusable, excessively oiled air filter. The MAF, GPS reading should be compared to a like vehicle with a OEM air box and filter under the same driving conditions to verify the concern.

Transmission or engine driveability concerns that are the result of the installation of an aftermarket reusable, excessively oiled air filter are not considered to be warrantable repair items.



Have you attempted to contact the manufacture to see if that would fit on your truck? As for passing emissions as long as it doesn't disturb how the air flows through the MAF sensor, you should be alright. To confirm, you should check the laws in your state concerning that.

This really is an automotive repair website dealing with factory manufacture designed vehicles and systems and how to troubleshoot and repair those systems. When you start getting into the realm of modifications and changes to the manufacture's intended design, you may not get good answers.

One good suggestion is to keep the old air intake ducting system just in case you run into issues or you want to sell the vehicle later.

Response From Hammer Time

This guy is just sucked in by all the hype nonsense and bogus claims.

He's spouted off long enough. Time to close this.

Response From Tom Greenleaf

Sorry for the harsh approach to what really should be a no brainer and no offence - the advertising is convincing with stuff but real results are so disappointing and costly to buy then don't work and costly to put back to what works!


K&N actually has a competitor for this market that's worse! Look up the Uban lore and myths of assorted products. Some you'll find great reviews but miss fine print that it isn't really tested and don't discuss it can also damage things for using them! Guess the budget for something is better spent not telling you that up front.


Makes this and other magic-in-a-can products a strong seller for the unwary. It's my/our fault to some degree that it's so clearly corrupted to sell this junk it gets taken out on the buyer who trusts the claims.
Graphs probably wont show below and I wont go looking for ones that will but if you really look into results of products of many assorted things never mind a vehicle that took mega thousands of hours to make and design as best as possible or loses a sale of a vehicle when new to another. It's suicide for a company to have an unhappy new vehicle buyer then the icing on the cake is nobody really want them used so really a disaster.


On just this air intake search I just did came up with OE air filter results done by real PPM of catching dirt and the CFM impact of air flowing thru filters and what loss would be expected at they were part dirty vs another. BTW in my hunt AC Delco came out on top of most testing! OE replacement stuff no alterations just quality of the product.


Changing to cold air just is beyond thinking it thru IMO and experience. Used to back when turn a round lid to an air filter upside down and get a neat carb/air intake roar with a load that did nothing but make noise and trash the filter fast but cost nothing and just put it back on properly was all you had to do so didn't do much harm short of getting a dirty air filter sooner and defeat WARM AIR pick up for cold starts and engine's initial time before whole engine warmed up and ran it's best. Do that stupid trick in the dead of Winter you would have real problems.


End all is the change you seek for whatever claimed benefit doesn't work and costs to do it then undo it when you find out. We really (or I was) were trying to warn you of a known failed idea not pick on you at all and did come out bit harsh. Sorry for that.


Try it if you want to find out for yourself. Measure before and after real changes yourself and then if you complain to this company bet you wont even get your money back!


Good luck. We really are all volunteering time and years of experience for that good no other motivation at this site,


Tom
Graph if it shows or search it out...........

Accumulative Gain:
“Accumulative Gain” is the total amount of dirt that passed through the filter during the test.

Response From Tom Greenleaf

They even advertise!

With honesty!

Response From Tom Greenleaf

IMO all that is junk you'll be removing later - don't even if it still runs well enough for an inspection it's of no use at all just costly,

Lost on this... power loss and misfiring

Showing 7 out of 7 Posts
Question From Nodd on Lost on this... power loss and misfiring

2002 Isuzu Axiom XS 3.5L v6 - Distributor-less ignition system, Coil-On-Plug system (each spark plug has its own coil pack)

Symptoms are loss of power and misfiring (P0300 random misfire), rough idling, when I put it in gear the RPMs drop to like 600 and sounds like it will stall. Check Engine blinks which means it is having misfires.

If I unplug any of the passenger side bank spark plug connectors it basically stalls out, but when I unplug any and all of the driver side bank spark plugs it doesn't stall and you can't really tell the difference.

What happen:

The water pump went out and the engine overheated. Me and my friend put a new water pump on, but it's behind the timing belt, so I brought it to a garage and had them do the timing. They said they hand cranked it several times and the timing marks were lined up every time. About an hour after this happen, I started it just to move it about 50 feet to another road and left it there. It was running fine.


What I have done since it's been out of the garage:

  • New spark plugs
  • New fuel filter
  • New EGR valve (took it back because it didn't fix problem)

  • Tested:
  • Compression (Each cyl was between 168 - 176 PSI)
  • Spark, coils (didn't check resistance)
  • Fuel pressure (42 PSI, specifications call for 42 PSI - 55 PSI, so we changed the fuel filter just in case)
  • Fuel Injectors (~76 OHMs)
  • Fuel Injector Connectors (with a NOID), all good
  • Air filter is good



  • Could it be a head gasket even if the compression was good?
    I don't think it's the cat converter because it ran fine before it overheat.

    Response From kev2 Top Rated Answer

    42 psi sounds low end*. try this check fuel pressure then with KOEO observe fuel pressure drop- lets us know drops xpsi in 5min.
    plugs - did you use correct plug? do not switch brands.
    are there ANY other codes- be sure code reader will read all codes.
    are the plugs on drivers side firing? easier said than done but a can do.
    might want to look at plugs- wet dry black tan-


    the flashing indicates cat damage is likely if not corrected soon
    *if your spec is correct plan on replacing pump as cold weather will be demanding.

    Response From Nodd

    I believe they are the Autolite Platinum, part number AP3924.

    There are no other codes. I have the Actron CP9125 OBD II code reader.

    Plugs are brand new, I used a spark plug tester on all plug boots and they spark.

    I'll check the drop in PSI tomorrow. Right now I'm thinking the garage didn't time it right, but the marks were right on all 3 pulleys.. I put it back together and checked them.

    Response From kev2

    your code reader - I think it is limited not capable of all codes esp manufacturers specific, those that could help with cam crank sync.


    your description suggests driver side is not firing.

    Response From Tom Greenleaf

    Autolite in this engine? Unless something new those are wrong plugs no matter what claims they had,


    T

    Response From Hammer Time

    I agree. That should have NGK

    Response From Nodd

    Ok, I will switch them out for NGK.

    I went ahead and brought it to a different garage because the only things I got it down to are timing and cat converter and no way the cat went out like that..

    The shop verified that the timing was set wrong. They said the pulleys are spring loaded and there is a certain way you have to do the timing on it.

    So when it's finished on Monday I will go back to the first garage with the receipt and demand a refund because the timing they set was way off.
