Yes, i did search but found nothing, as the title states my car has a rough idle from 1000rpms to 1600rpms. Some times it will idle fine though, i tried a different IAC vavle but nothing. And i also get a CEL for the Fuel supply system after my car sits for a while and cools down, but when it comes on if i shut the car off and turn it back on it stays off until i let the car sit for a while then it will come on again. Usually does it when it sits over night, then comes on when i start it in the morning, it takes a couple of miles though before it comes on. i think it was CEL 18

 

BUMP, no one can help me?
