Hey all working on a 04 pilot with a slightly rough idle, didn't have a code for it but tried replacing it, anyway. No luck and now it throws a code for the IAC circuit after replacing it, it also has a temp code 1399 misfire in any cylinder. That didn't show up in the temp codes before though, and with the new IAC on it has that typical idle bounce which it didn't with the old one. Basically it has a slightly rough idle and the idle drops down really low when you put it in reverse but picks back up after a second or two. Any ideas?
