belo4884 Posted September 28, 2004 Report Posted September 28, 2004 I have a 94 Cutlass 3.4 DOHC and yesterday this started out of no where. When idling it will run for a couple seconds and then the rpm's will drop, will come back up, then will drop again and it will not recover and it will stall. I already checked the fuel pressure and it is fine (~40psi). When driving the car, it runs fine but if you go to accellerate it will hesitate a little bit. Please offer some suggestions. Thanks Quote
White93z34 Posted September 28, 2004 Report Posted September 28, 2004 i'd check your IAC and TPS Quote
belo4884 Posted September 28, 2004 Author Report Posted September 28, 2004 i'd check your IAC and TPS What am i looking for? Should I take them out and clean them? Quote
White93z34 Posted September 28, 2004 Report Posted September 28, 2004 the iac and tps are 2 sensoirs located on the throtle body, iac is closer to the top and tps is below it, try cleaning the iac and the tps oh and is the car throwing any codes? Quote
belo4884 Posted September 28, 2004 Author Report Posted September 28, 2004 Nope, no codes. I will look at the sensers when i get home. Thanks Quote
sonyman87 Posted September 29, 2004 Report Posted September 29, 2004 my bets on IAC Idle air control plunger is probably screwed up or is plunged up and cant move. Quote
belo4884 Posted September 29, 2004 Author Report Posted September 29, 2004 Well I clean the IAC and the TB(cause i was there) and no results. I also made it relearn the idle, but that didnt work either. So i am pretty sure that it is the IAC. Thanks for your help will let you know if it worked. Quote
