does 1996 infiniti g20 have a coil wire?

Showing 5 out of 5 Posts
Question From chrisser42 on does 1996 infiniti g20 have a coil wire?

I replaced the spark plug wires on my 1996 infiniti g20. included in the set is a coil wire. does this need to be replaced? does this car have one? i have looked and do not see where it might be if there is one.

my car still runs rough like one of the cylinders is not firing. I have also replaced the spark plugs. I am hoping that it is not the fuel injector.

thanks-

Response From Tom Greenleaf


Car did show a single coil like above so the wire goes to it. If you feel ONE cylinder is being singled out for a misfire it probably isn't the coil wire but you have it so replace it anyway.

If no codes and you really think it's one cylinder look at the plugs - one will look different if the problem is there it could be the plug (do all if any) but take note of the wear on each as it can tell what to look for next if not a plug itself,

Response From chrisser42

ok, thank you. where would i find the coil?

Response From Tom Greenleaf Top Rated Answer

I just looked for parts to see how this was set up but don't have a complete pic of engine compartment. All showed this coil and that a wire went to it so it's up to you to find something that looks like in the pic but OE probably was all black.

It about has to go directly to the distributor cap itself as it listed a rotor in there too but cap in the pic I saw didn't have the common coil wire up top in middle of the four plug wires so look harder! Does it sneak in the side or from under but still to that cap?

If you are chasing down this problem you really should look at all the tune-up items and replace all that are necessary. Remember - no matter what happens with ignition only the spark plug itself touches the fuel mixture with spark as the end of the line for ignition. They are informative of what MIGHT be wrong.

Seriously - if you don't happen upon what's making it run rough then get some help soon. Waiting could cost you zillions in fouling up o2 sensors, cat coverter that could be avoided,

Aftermarket vs Remanufactured fuel linjector?which is better?

Showing 2 out of 2 Posts
Question From alexjones on Aftermarket vs Remanufactured fuel linjector?which is better?

Hi ,
I have 1993 infiniti G20 with 215,000 miles. I am going to buy a fuel injector online, which one is better to buy ? the New aftermarket or Original used remanufactured?
I am worry about aftermarket part not fitting perfectly and having a fuel leak problem later.
I would like to hear your thoughts please

Thanks
Alex

Response From Discretesignals Top Rated Answer

Buy them in a set and replace them all. If you only do one and you have 215K miles on the old ones, the flow rates are going to be different.


I can't tell you the best way to go when buying injectors. One thing about reman injectors is they can only do so much, such as : sonic cleaning, checking coil condition, replacing screens, and flow testing them. If you go the reman route, make sure it has a good warranty.

New would be ideal if you can afford it.

Another thing on those Nissans with side feed injectors is to make sure that you don't have any leaks when you put it all back together. I suggest you either connect a fuel pressure gauge up or pressurize the fuel rail and watch for leaks before you bolt the rail down and crank on your engine. If you have a bottom injector o ring leak, it will fill up the cylinder with gas and you'll end up hydro locking and possibly bending a rod.

Runaway idle /EFI/ throttle by wire

Showing 2 out of 11 Posts | Show 9 Hidden Posts
Question From Joeb1983 on Runaway idle /EFI/ throttle by wire

2006 Infiniti G35 coupe. (350z)
3.5l, VQ35DE revup
6 speed manual
58k

Engine RPM rising with no accelerator pedal input.

Lift off gas, put in clutch, RPM will hang and then rise to 4, 5, 6, 7k...

If I pull up on the accelerator pedal hard, bending the armature RPM's will drop.

To me I thought it was a bad accelerator pedal position sensor...

I replaced the entire pedal assembly given you can't just purchase the sensor alone and seeing how the sensor is indexed in the bracket/mount.

Drove the car for about 5 minutes after instal, seemed fine and I thought all was well, so I drove it to work.

After around 30 miles stopping at a red light RPM's started rising again...

Pull up HARD on the (new) pedal they drop...

It will slowly rise to the limiter if I let it...

Any ideas?

MAF is fairly new. Less than 3k.

Response From Discretesignals

Does your scan tool have data stream capabilities? If so, you should graph APP 1 volts, APP2 volts, TPS 1 volts, TPS 2 volts, actual engine rpm, and desired engine rpm. See what those pids are doing when your problem is occurring. Maybe that information can paint a better picture.

Probably would also be a good idea to scan for codes on the manufacture side. Sometimes manufacture codes don't show up on the OBD2 side. You need a enhanced scan or the factory scan tool to get more information.

Response From Joeb1983 Top Rated Answer

My scan tool has the ability to view live data.

I also have tuning software that has all the features of consult II. (However I can't get it to open after upgrading to Windows 10)

I guess that gives away the car is not stock...

This is where I usually lose peoples help or go on a wild rabbit chases.

Given its been fine up until now I figured it had to be a simple component failure unrelated to the modifications given all had been completely fine up until now.

Here is a condensed list of mods. Any specifics feel free to ask if your still with me. Haha!

Vortech supercharger
Walbro drop in pump (255lph)
Injector Dynamics 725cc fuel injectors.
UpRev GT MAF (recalibrated OEM)
Full exhaust (headers , cats and exhaust)
Jim Wolf technologies clutch and fly (dealer installed)
UpRev Osiris tuning software (unlocks and re-flashes oem ecu)
Very conservative dyno tune from a world renowned tuner.

Viewing live data I don't see anything crazy. Ignition advance follows RPM, MAF is not erratic, coolant temp, IAT all steady and nothing high or low.

I can't view APP only TPS and It seems to correlate. It's a gradual rise in RPM; maybe 1k per 1.5 - 2 seconds so it's not a huge increase.

I wish my software worked. I can log no problem.

I see no fluctuations with vac and I have no boost leaks

Response From kev2

"Given its been fine up until now I figured it had to be a simple component failure unrelated to the modifications given all had been completely fine up until now"
you are discounting that a modified component has failed- They are the most LIKELY to fail.


getting the scanner working is key, I wonder if the throttle plate is actually moving OR something causing hi RPM,
look at the throttle control motor - is the circuit ECM to motor actuator , open, shorted to power, look at trouble trees p2100 and up as that is the fly be wire system wire colors ECM pinouts, tests etc....


GTG first susprct is always aftermarket

Response From Joeb1983

I see what your saying, I just have a feeling its not the blower, fuel system or exhaust causing the issue.

I'm not even in boost when it ramps up.

I have wide bands and I don't see any fluctuation or any lean or rich conditions from target AFR's.

I'm un-installing and re-installing the software now.

Response From Discretesignals

Just like with any drive-ability problem, the first thing is to identify what is causing the concern. You need to start here first before guessing and swapping things. Collecting data from suspected systems, doing visual inspections, and interpreting data to figure out what is going on is important.

Once you identify the what, then proceed to figure out why. Once you isolate the why and repair it, then figure out why the why occurred, so it doesn't happen again.

Sometimes you can get caught up in rabbit holes diagnosing stuff. That is where thinking outside the box is helpful. If you see things in data or reactions by something that don't make any sense, sometimes resets can fix the issue. I've run into a few vehicles that doing a reset by disconnecting the battery, touching the terminals together, and turning on the ignition for a period of time, actually corrected the anomalies. Somewhere in software or logic functions the PCM gets caught up in loops and does strange things. Why this happens I don't have a clue. Fully powering down the PCM, just like your PC, can bring things back into order sometimes. Recognizing the weird things that are unusual come with experience. Sometimes connecting a certain brand of scan tool or device to the OBD2 connector or even accessing certain modules can cause all kind of weird things to happen.

Our shop uses an Autel scanner and the other day I connected into 06 Hyundai Santa Fe. When I did a full system scan the engine shut off. I noticed the engine shut off when the scanner was getting codes from the immobilizer system. I didn't condemn the vehicle. I suspected it had something to do with how the scanner communicated with the module. It was repeatable of course. Just so many variables to deal with on these vehicles and it gets worse with modifications.

Response From kev2

sorry I had to go... What I was thinking was


Because the ECM sees no conflict between APP and TPS I question if the throttle plate is really moving. and something else is causing RPM.


The RPM ranging up may require several incidents to set codes they are NOT 1 failure type.
I think your pulling up on throttle is causing a out of range issue and the ECM defaults - the issue causing high RPM is no longer present, the one time pulling on APP assy would not code and you return to 'normal' .


have you looked at MAF - is it gong up as RPM goes up?
With a blower positive manifold pressure how do you handle EVAP purge, and similar functions?

Response From Discretesignals


This is where I usually lose peoples help or go on a wild rabbit chases.

That is perfectly understandable. Most of the professionals in the auto repair industry don't get too many modern modified (electrically and mechanically) vehicles in the shop or even want to deal with them. Modifications open up another world of possible problems. Once you start getting into software changes and other mods, the factory repair information becomes useless.

I know that in factory software, the PCM is monitoring the correlation between sensors to be sure they are in agreement. If the PCM sees an increase in idle speed or rpm, but doesn't see APP voltage changes, it should go into reduced power mode and either fix the throttle position or kill injectors. It should also flag codes. If it sees sensor correlation errors or sensor circuit issues it should do the same thing. There has to be redundancy for safety. It is how the factory software is written. When software is altered or modified, it is possible those parameters for TAC issues are not included or altered so they don't perform the same way? Hard to say without knowing exactly how the modified software is written.

If it was factory software and you had no error codes or reduced power messages, I'd say yes, the PCM is seeing an APP1 and 2 change for some reason and bringing up engine speed. Then you need to find out what is causing the voltage changes for APP inputs. Really don't know why pulling on the accelerator pedal causes the engine to come back down, unless you're changing the APP voltage input voltages into something the PCM software doesn't usually see or recognize.

If you had a 4 channel lab scope you could also scope the TPS and APP sensors and actually see if the throttle is opening and causing the higher idle or if there is something else causing the engine to idle up. Really need some data from those sensors. Probably would also be interesting to see what the injector pulse width is doing if you don't see changes in TPS voltages or throttle percentage during the idle up concern. You also have to know what those voltages should be normally, of course. Need a baseline to work from.

Response From Hammer Time

If you haven't done it already, have the computer scanned for codes.

Response From Joeb1983

I have a scan tool and there are no current or pending codes unfortunately... (should have listed that)

Appreciate the reply.

*** I also should mention I have performed the accelerator pedal position reset as well. ***

No fix.

Also, RPM is not searching nor erratic. It's a smooth increase just as if I was slowly pressing down on the pedal.

Pins on both connector arnd sensor are not receased, bent or broken.

The thing that stumps me is why does the RPM drop if I pull up HARD on both the old and new pedal assemblies.

They both are at their mechanical stops... Plus, again this is a brand new assembly doing the exact thing, so obviously that was not the issue.

Response From kev2

my first thoughts....
Is your 'scanner' up to the job? these codes will likely be so called manufacturers specific.
Also will scanner allow you to view 'live' data - ?
important- vehicle is STOCK ?

Question From alexjones on ​Buzzing noise when push the accelerator and when the key is in "ON" position

Hello all,
I have 1993 Infiniti G20 : 215,000 miles.
the car was running very bad. shaking hard when driving, for starting the car I had to push the gas pedal while cranking so the car will start and sometime when I was getting to a complete stop ( on red traffic light) I had to change the gear to Park to prevent the car from turning off. anyway, I found out one of the injectors is bad ( the resistance was 114 {normal is about 10-14})and was not clicking. so I took of the fuel rail and tested the injectors by connecting a 9V battery . 3 of them shoot out gas but that one broken one didnt do anything. so I put everything back together till I get the replacement injector, and now when the key is in ON position and as I push the gas pedal just a little bit a Buzzing noise comes out from underneath the hood ,I couldnt pin point where it is yet. also now I am having very difficulty to start the car. feels like it is out of gas. and when car starts after couple of pumping the gas pedal while starting , giant white smoke comes out of the tail pipe and strong gas smell .

I would appreciate any help.

Thanks
Alex

Sport - Pumping a fuel injected engine does nothing but exercise your foot unless to the floor to clear a flooded engine.


Buzzing noise - no clue yet for you. The white cloud out tail pipe isn't a good sign as you should know. Not much other than a blown head gasket or crack that allows coolant to get in can do that.


I suggest doing a compression test to see if this engine has some totally out of spec readings. It's old enough with some miles to be considered how far you want to go with it IMO,

Thank you for your reply T , the white smoke goes away as soon as the car runs for a few seconds. and I am assuming it is because the gas pedal pumping but I dont know. as you said it is an old car I paid $1000 for it and I hate to spend couple of thousand to fix everything, I just wanted to fix it to run almost normal so I can sell instead of sending it to junk yard.

The "white" smoke may have an odor and also might go away after start up and stay gone.


Would think you'd be noticing loss of coolant if it's done that a while. The rest is I think this engine is all confused as it's relying on normal compression and normal intake manifold vacuum for lots of operating functions even in 1993. Try for codes for an area of a problem noted but the white smoke is the killer.


If you've disconnected the battery or it's gone totally dead anytime recently I'm near sure this car will forget how to hold a normal idle having lost memory that over time and use covers the changes of slowly getting dirty in throttle body and other things like plain load on engine from accessories or just sitting in drive vs a neutral.


Pull plugs at least and look for maybe one only or more that is too clean or worse plain wet with coolant. Pressure test could find it and could (if bad enough) fill a cylinder with coolant and lock engine?


There's a list of maybe things but not a whole long list on why it could blow that white smoke. Check oil for contamination too.


Fuel injectors can if before you found a bad one have been flooding the thing washing lube of that cylinder badly and you'd find it way off now.


Just check easy stuff as I do think you've got some bucks ahead that might be more than you would want to spend on this exact car. It's worth bucks (for metals if nothing else) as scrap priced local to you.


Miles alone don't matter way too much for a very well cared for car/engine but time counts and stupid stuff like even the seats lose it, knobs and handles only take so much and get annoying - your car, your call but find out what you can before tossing bucks at it,

Thank you very much Tom for taking your time and explain it to me. you are right I dont want to start spending on something that might or might not work.
I will do the check list you said. the one good thing this car had when I baught it was the full repair service manual and that is what I had been using to fix stuff on it .
The book probably worth more than the car itself now :)

It's not over yet just need to find out where you stand. Great that you have manuals and no doubt worth something. Sorry if I'm stuck right at the "white smoke" but it's the most important thing to know why. You did say it smelled like fuel which would be dark and sooty unburned fuel. If extreme enough probably soil a cloth for a close look.


It doesn't take much coolant to make a cloud of smoke nor oil. It may be confused with the standard color of what you see and going away once finally running can happen.


OK - Consuming some oil may not mean too much by some miles but shouldn't really be seen and always note how long or miles it takes for oil consumption. Coolant really shouldn't use any but rather just expand with heat and contract with cooling off at close to marked levels of tank AND remain always full at radiator.


Spark plugs are very telling of what is going on inside cylinders. Even if older you look for them to be the same unless clearly ONE cylinder shows lots different from others.


Try to do as much diagnosing as possible while it's intact and running as that ends if you have things all apart.


Stinks but could take a while. If running poorly you risk the cat converter(s) too. No problems from me keeping and using old vehicles some had some much higher miles than this but a history of most since new on many of my own on most which helps some.


Add any recent work that might be a cause of something now that's overlooked too,
