My Car Can't Idle
Thursday, April 27, 2006 12:32 PM
Okay, 1998 Pontiac Sunfire 2.4L twin cam automatic.

Now, i'll turn on my car.....Will run like normal for about 30-45 seconds. Then, RPMs start to drop alil. When it drops to about 400 it fires back up to about 1400, As if the cars trying to correct itself. Eventually, it'll stall out

If i drive, it'll spit and such, and if i push in the gas, it'll just drop and dog down, unless i floor it. If i floor it, it'll take off.

While i'm driving down the road?....its fine. Seems to fun just fine as long as i'm above 35MPH

What the heck does this mean?....No check engine light whatsoever. I checked all the vacuums, and seemingly fine.

Opinions please =(


I love to smoke Civics!...........In reverse =D

Clean the IAC(idle air control) on the front of the motor and reset the computer. Could also be a dirty TPS(throttle position sensor).
