My '94 GT was having trouble holding idle this morning right after a cold startup. It would die unless I held the gas and kept the RPMs around 2000. If I let off the gas, the RPM's would drop to around 200 and then it would sputter out and die. After about a minute, the problem went away.
According to some research on this board, it's the idle air control valve. I read some references to people stating they were going to clean it or did clean it, but I didn't see any information on how to actually clean it. P.S. I just put new plugs in, and a cap and rotor. The problem above only happened this morning and about a week after I gave it the tune up. I have only owned this car a month, but I have noticed the idle seems to drift a little--sometimes it's idling around 500 and shakes the car a little when fully warmed up, and sometimes it idles just fine around 800 when fully warmed up. Before I actually replace the IAC, I want to try cleaning it but want to see what others have done. Once I clean it, then I will re-check the timing. |

Thank you guys for your time in helping me with my cause.
The level of pain in the ass it was to get to the iacv just today is somewhere between helping a friend move and dealing with a tax attorney. I'm just over messing with it anymore because my old girl runs beautifully, just one flaw that I've lived with for 3.5 years and will continue to live with because nah, I ain't doing that again. Again, thank you for your time in helping me, it goes greatly appreciated. -------------------- Brand new 6gc owner! (sort of 2011)
