SORRY! GUYS! Idle Air Control Valve was the problem..... THATS IT! Should take you about 30-45 mins to fix :).

why was your IACV not a problem before you disconnected the battery?

steviej

Just a guess- its probably because of the way they work- they allow a certain amount of air in and mine was covered in carbon. The computer over time had told it to open more to compensate for the carbon, however when I disconnected the battery, I assume that the computer was saying "hey, you cant open that far that fast! I am just idling!"

hate to tell you stevie,

Iam 99% sure 02& 03 do not not have a IACV
