My 96 eclipse GSX recently decided it doesn't want to idle. It does start from cold (choke keeping idle). After it warms up, it won't start unless I give it gas. And while driving, as soon as the clutch goes in, the engine RPMs drop right to 0 and it shuts off. Does anyone have any ideas? Could it be a sensor? I haven't changed anything for over 3 years. It runs fine except it won't idle. Mods have been K&N filter, Greddy BOV, boost at 15psi, hard IC piping, full turbo-back exhaust. All this was done over 3 years ago with no problems since. Thanks, Aaron

 

if your venting your bov try adjusting the bov or is you want better performance dont vent at all. if thats not it check all vacuum lines

 

My BOV is recirculating. I already did a quick check on the vacuum lines and IC piping. All looked OK.

 

hmmmm....no leaks at all??[:-] try to re-set your computer...

 

check your BISS, o2 sensor, and make sure your maf is plugged in all the way

 

idle speed control possibly bad.. not too uncommon

 

Having this same problem with my 2003 GS. Found out today the idle sensor needs to be replaced. Check your coolant levels too as I was told my engine got too hot and that fried my sensor.

 

I checked both the TPS and IAC and they measured fine. Cleaned the throttle body and stuck it all back together. It worked for about 5 miles then it won't idle. Checked the IAC again and one of the windings was open. I'll update this thread after I put in a new (or used) IAC. Thanks guys!!

 

I had this problem shorlty after I got mine. Someone told me the fuel control valve.. Then I was told it could be a sensor.. And in the end, my motor was on its way out... A week later I had to replace the whole motor, b/c a piston hit a spark plug and I lost compression in all the cylinders...

Not a cinderella story

 

Finally got an IAC off ebay. Everything is working fine now. Thanks for all the help.
