New Problem

Ok guys, synopsis..1995 2.2l 185,000 changed plugs and wires..,one of the wires had broken off and was stuck on the plug, car is running strong..however when i just barely give it gas it acts as though it wants to stall..no other time does it do this..but if i just touch the accelerator to go less than 10 it starts jerking.

Work done on car to date:

Replaced: Head Gasket, Heater Core, PCV Valve and fuel injectors (3)

I used some fuel system cleaner and I'm wondering if this stuff has somehow clogged up the fuel filter..

Can anyone give me symptoms to when the fuel filter is clogged or when the IAC is not functioning properly..I want my baby to run right and I know that ya'll have the no how to help a chic out

Well...........
1. If the car runs strong above idle > 2000rpm...then more than likely it is not the fuel filter. Although it should be change every 25K miles. Some are a real pain to get off !! I have broken at least 5 of them.
2. Is the CEL light on ???
3. You can guess all day and hope to find the problem. But the first thing a shop will do is scan for codes. Some 95's came with a OBDII connector, and you can actually scan it as a 96. My son has a 95 Pont.FB and I scan it all the time.
4. Have the plugs been changed recently ??? Maybe the plug with the bad wire is now fouled...this is a cheap fix. 4 plugs = 8 buck.
5. If you reallly want to be a DIYS wrench....spend $20.00 bucks and buy a manual for that car.
6. Lastly....go to AutoZone.com...they have a great repair/how to section for that car. I use it all the time.

If all else fails.......go buy a 12 pack, the car won't feel better...but you will.

Opps my bad....I see you did state that the plugs/wires were changed.

But this can create a new problem...ARE U Sure....the wiring is correct ???
Double check and then check again. The coil packs on that car are hard to see from the top and bottom.

I have heard of this prob. before and as I have understood it that no one has a cure for it . my new rebuild does the same thing but only when the motor is first started up cold. you know that little touch of the gas pedal to get going and then I have to accel past that certain point.
Well I think that it would have some thing to do with the throttle position sensor or some related tb situation . I am still working on other stuff for the car so that is still on the bottom of my to do list. Oh and I have the 2.4l motor. I'l let you know if I happen to stumble accros the fix... ha ha!

ok another thought and it lead me here pg. 6-4 Haynes manual #22 Idle air control (IAC)- the iac valve controls the amount of air allowed to bypass the throttle plate when the throttle plate is at its (nearly closed )idle position.The iac valve is controled by the pcm. When the engine is placed under an addtitional load at idle (power steer, a/c, low speed manuvers) the engine can run roughly or even stumble and even stall. To prevent this from happening the pcm opens the iac valve to increase idle speed enough to over come extra load.
Imo : this is why you hear everyone talking about removing iac and make sure it is clean with all the dirty air let in and crap that builds up on it.
I guess I will go ahead and remove mine and see. Even though I had the Tb off and clean the hell out of it. I did not actually pull the IAC valve out and clean the valve its self thinking that spraying from all around would work during my rebuild so I will post back after while.I am also installing a ETC sensor at the same time (rad fan stuff)

I'm going to replace the IAC and see if that will fix the prob. If you do it first keep me posted and let me know how it turns out. @ Helmuth..if I liked beer I'd do that...I'm a Vodka type girl...LOL

usually you will get a code for bad iac ,it may just need a clean. I fixed my fan prob but in the process heated car up and I did have the same prob. (stalled even died )this time on cold take off earlier. I hate doing two things at once trying to cure probs no time to explain see sig waiting on car to cool off before I try again> at cold take off and I did clean iac to much tb cleaner I think bad results

Vodka....nothing wrong with that !! If gas keep going up....it maybe cheaper !!! Let us know if the NEW IAC worked.....I hope you did not buy something you did not need....where cleaning it may have also worked.

I took out the old IAC and it wasn't the 1.10 calibration that it was supposed to be, don't think I can pull it out..:dunno: I put in the new one and it did some hesitation not as bad and this morning none at all..so maybe that did the trick.

I do have the CEL on, but when I took it to Autozone they can't get the computers to communicate so go figure..this light has been off and on for months now.. will keep ya'll posted...

Weathers going to be about 82 today...yipee

OK...good, you installed a "used clean" IAC and the car is running better..sound the a winner to me !!! I will drink to that !!..hic, hic

Just wondering about the OBD connector in your car. I know that GM install the OBD II connectors on some OBD 1 systems in 1995. The 95 Firebird my son has....has a OBD II connector under the dash.

So when I use my AutoXray 2000 Scanner, I used the OBD II connector to the meter and configure the scanner as a 96 instead of a 95 and it works !!!!

Good Luck,

let us know about ur code. My car was better this morning too but still some hesitation please see tsb on www.quad4forums.com (http://www.quad4forums.com) writen by EPA NIGHT MARE on 2-21-2007.It talks about oil pump causing to much pressure on cold start causing lifters to float? and stall motor check it out. But I did install a new oil pump after market on my rebuild, maybe they just copied oem spec's Iam such a pessimist

I'll check that out..the first time it threw a code it was a 030 but I didn't see that in the Manual..they read it as an EGR valve code..I guess that will be my next (probably should have been my 1st) repair..

ok the tsb is 77-61-09B oct97 it has to do with oil pump pressure relife valve not working ,relieving excessive pressure anyway I could not get to that page it was on by that search method. I tied a search for researchers wanted under 2.4 problem diagnosis you will like this place too.

Oh for the love of all that is holy:banghead: :banghead: IAC didn't work..I wonder if this could be a TCC solenoid issue? I'm doing Tranny change and if possible will also put on new TCC solenoid and see what happens..

This car is making me :runaround: :screwy: my left blinker went out too...I'm going to :smokin:

lets do it again because I am also not happy with the results I got so far either. Repeat: for new readers cold start and slow idle throttle up to say 15 miles an hour. the vehicle acts like it wants to cut out but when giving a heavy throttle it goes right past the stammering and cutting out part. It only does this when cold any new help would be great !!! Ihope you do not mind daughterisis313
I my self do not think that the TCC would cause this as it would be more like a slipping tranny than that miss like prob.. Besides new tranny you should not have to install new TCC. lets burn one.
New parts on mY car ETC, TPS (code), crank sensor (rebuild) knock sensor (rebuild)

Ok guys, well I think I've found a solution for the jerking although the problem isn't "fixed" I noticed that when I turn on my AC my CEL doesn't come on and my car doesn't jerk at low speeds. Anybody know what may be the common denominator here? I ran my AC all day yesterday, no CEL and no jerking the entire day...thoughts?

Helmuth48

G'Day missus.... If you solve this issue...it could be a BIG help to alot of wrenches .....
FACTS:
The Idle Air Control (IAC) stabilizes idle speed during cold starts and once the engine is heated, to stabilize the idle when a load is put on the engine (i.e. when your air cond. comes on). It allows air to bypass the throttle plate, thus giving the engine more air when it needs it, such as on a cold start or when there is a load on the engine.

While your IAC is part of the Emission Sub Systems, and is, in most cases, controlled by the ECM/PCM (Electronic Control Module/Powertrain Control Module), it is usually diagnosed with a scanner.

Sit down with a Vodka-Tonic, make it a double.... and go through the phone book and find a shop that can Scan your OBD 1 system.

It can be diagnosed without the scanner, but as the symptoms may be caused by other sensors and/or components, you do run the chance of a misdiagnosis.

Well I give up ....after compression test valve checks and another set of new plugs the car is at the DEALER of PAIN ....pain in my ass where the money ought to be .........so we shall see if they can figure it out 80.00 dollars an hour

after all said and dune FPR :thats FUEL PRESSUIRE REGULATOR cleaned injectors with TB cleaner and air both ends of injectors also put in new injector o-rings while I was there. MAJOR differance very nice like there is a new motor in this car. I my still have an injector issue but this fix was very notable for me

HEY ISIS313....... put it in and give us a shout!!!!!!!!!!! FPR

Same ol stuff going round and round lost in the woods!!!!!!!!!!!!!!!!!!
Living in fear of the stumble .The car started screwing up again and so we went back to the dealer for help and we checked and came up with computer problem so I got that changed and had to have the computer flashed for cranck sensor re-learn again .ran good for about a day and once again started screwing up well I thought fuel but no it was not the fuel pump because as I poured fuel in thr intake it just bogged down. I did this because I no longer had just a slight miss this has gone to a major miss from what I got from the dealer 1&4 cylinders where missing (when it did miss) so the only thing I knew to do since the ICM was in control of 1 & 4 ...2 & 3 this from computer was I just replaced everthing under the IDI and boy did it run good again untill the next day.when I went to move it and it shot me a crank sensor code and now it is back at the dealer for poss. new crank sensor that is new with rebuild. hell the dealer has to flash a re-learn for new crank sensor any way. What luck what skill sombody just lay hands on this car...this thing has barley run since in stalled what a learning experience this ain't your MOMA"S V-8 SORRY for stealing this post and thanks for the vent DAU. 313

Wow, I just give up. I took "Becky Sue" down the road to Myrtle Beach and she ran like a champ, Check Engine Light on and all...so right now I don't know..she runs better with the AC on than with it off..I guess I may have to go to the evil "mechanic" and get a diagnostic
