Take a guess....

u can also take ur air filter off and smell for gas wen u open the throtle:th_thumbsup-wink:

I would take a vacuum pump and put 20" of vacuum on the fpr and see if gas leaks out the vacuum line port on it. Some you could not tell buy just pulling the line, like my grand am.

I'm just gonna sell it. I'm done with it. It's a piece of crap.

 

[gtpinsc]

quitter. its prob somethin easy as hell to fix.

 

[imdaman3]

didnt smell any gas from the intake r vacuum lines??????????

 

[JESSEGOTTA GP GT]

Yeah and I bought a new pressure regulator and it didn't help at all. I've replaced everything "easy" to fix the problem.... Unless I missed something?

 

[imdaman3]

wats it doin again excatually?? could u have a clogged cat or bad fuel pump??

 

[JESSEGOTTA GP GT]

It's running smooth and fine as can be. Sometime (maybe once a month) if I'm sitting in traffic for a while with the a/c on full blast and just give it enough gas to move forward 6 feet it will almost stall, then the rpm's will shoot way up to 3k and then it goes back to normal. Other than that it runs perfect.

idle air control valve,, take it out and clean it or replace it

have you checked your fuel trims and also see if it goes into closed loop?

I already cleaned it, but I got one off a 01 GP in the junkyard with 69k miles. Everything I clean/replace helps a little bit but doesn't fix the problem.

Dont I need a scanner for that?

He probably can't...and yes you do.

 

[JESSEGOTTA GP GT]

I know a few people with a GM tech 2 scanner I can probly try to get my hands on and see. But I don't think it's anything that complicated.

what i can see is that you say the car runs good which means the air/fuel mixture is good. but maybe burning a little too much fuel whch at the same time taking in more air. any scanner that shows datastream will show you almost every important sensor input on your engine that even includes wether its closed or open loop. i have an actron scanner that shows all this stuff. has helped me out a lot in a lot of troubleshooting that cant be fixed with just going by basic stuff.
