If I'm cruising along and push the clutch in my car will idle really low and eventually die. If I'm sitting still it will idle just fine. I've hooked up an OBD2 code reader and it doesn't pull up any codes. Any help would be appreciated.

 

is it turbo'd? what mods do you have? My car does that but thats because I dont have my idel control sensor hooked up.

 

clean your IAC (if your car is equipped with it) pull the large hose off the intake hose and keep the car from stalling, now spray carb cleaner in the hose for a couple minutes, while keeping the car running.
