Ok. I know this is a common question, which I searched for, and can't remember how.
How do u check what the code is again. I cant remember how to check it with the key thingy. Lol
Having rough idle problems after I went trail muddin this past Sat.

Found the code.. P300 multiple cylinder misfire..
Plugs and wires replaced in Aug 13, is this a coil pack issue or do I need to replace the plugs and wires?? Any thoughts..

Twice over the last 20k miles I've had that code pop up. Its been right after startup in the morning both time... the idle drops down and I can feel the engine stumble, light comes on, and everything goes back to normal. Could be anything, so I choose to ignore mine till it becomes more regular
Is yours doing it regularly?
