1994 camaro 3.4 auto.i just replaced the plugs and the fuel pump and the car was great.then out of nowhere it shuts down in idle you have to give it gas to stay runnin and when you start the car.it will start if you give it gas and hold it.when i rev it high rpms i can hear a slight whistle like a leak but i have no idea where to look.all help appreciated thx if i left somethin out let me know pls.

 

Check all the vac lines and rubber hose connections on your engine. You could have accidentially pulled a line or hose off it connection while working on the car.

 

Does that "out of nowhere" have anything to do with it being after the engine warms up nearing running temperature, or is it random?

 

sry bout that is does it cold or hot.everytime i try to start the car is shuts off but if i give it gas it runs.i will check the vacuum tomorrow.thx

 

Did you install your fuel filter backwards?

 

no the fuel filter is on correct.the car ran fine for 3 months after all the work and then it started havin this problem on a side note i can unplug a vacuum line and the car runs better but not 100 percent

 

what vacuum line do you pull off

 

the one that v s off the center off the intake or the brake booster line.

 

i think thats the heater/ac vacuum, does it go into a wiring harness. did u plug the vacuum on the intake?

 

when i removed the vacuum lines i didnt plug anything and i looked at the fuel pump again and the only rubber line there is i unplugged it and it relieved the air(hissing sound) in the tank and it runs fine until the pressure builds back up again.
