Need Help Idle Problem - SRT Forums

boostfan4 · 10-04-2008, 04:05 PM

I was hoping a local homie can help me with a little problem I'm having with my car. It drives normal until I put the clutch in when i'm coming to a stop the rpms will sit at 1400 rpms until I make a complete stop, as soon as my car makes a complete stop the rpms drop to normal idle. Im thinking maybe tps sensor? I've already tried the tps harness, that seemed to work for a day then it started doing it again. It actually started getting worse today now when the rpms finally drop after the car stops it now only drops to 1000rpms. the car has 98,000 miles and has always been good to me I just hope the car doesnt go down here from here. thanks for anbody that can help

tps or bad iac, check for vac leaks too

check all vacumm lines. like pcv and what not. you might also have a dirty throttle body. clean it.

when you check for a vac leak, check for cracked lines.

i thought my car was the only one with this problem.
Ok so, i have this problem too,i tried the TPS thing and it didnt work,idle goes up a little higher then 1500 rpm,im runing my car with Stage2 kit,one day i had to switch from stage2 to Stage0(stock pcm and sensors),and drove it for 2 or 3 weeks with Stage0 and never had the problem again,so i guess it could be one of the sensors of my stage2.
But now, i have the Stage2 back in the car and i havent feel the problem again.(for now).

So i just wonder if you have Stock ECU or Stage kits?

oh yeah,i've been told about throttle body could be dirty. but i havent clean it.is there any product to clean throttle body and how to?

just take it off and clean it with brake cleaner. get all that grime off. MOPAR use to have a combustion chamber cleaner. i used it twice on my firstgen and never used it again. it was bad for some reason.

Sounds like the TPS, contact S&P for a fix it kit.
