Thanks guys for all your imput! I think I will start with the basics and check the plugs and wires. Its funny how it not always idles rough. Last night I drove it around and it acted fine. I was thinking it may have been b/c I washed the engine a few days ago and maybe some water hit a bad spot. Anyway after dealing with the plugs/wires if I still get the check engine light- I'll get the codes read to give me a better clue whats going on.
