my sc got the idle problem. when i start the engine first in the mornig, there is no problem. but sometimes after that, when i start the engine, the idle is very rough. the idle moves between 600 and 400rpm. so i hit the gas pedal till 2000rpm, then make it stay there for about 10sec or so, and release it. it works fine. does anybody know what the problem is?
 
What year car? I have similar rpoblem and believe I have an EGR problem. No one here has them though checked today.
