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 Scott
