Well ive been having IAC problems for a while now. I replaced the IAC about a month ago. For a week or two the idle still dived a little bit so i check all the vacuums and everything. It quit acting up for about two weeks and all a sudden yesterday it started the idle diving and it died on me tonight. One thing i think it might be is that my car was hit in the front side and messed up my CAI so i cut it off into a ram air ever since then i have had these problems is it the intake or what?
