Ok so I replaced the IAC didnt change anything on idle. Did the reset and achieved beautiful idle once again but when I shut it off and then restart it goes right back up. So now I have 2 new IAC's and one of the original ones that was in it did the reset on all 3 of em and got a great idle but once restarted its nice and crappy again. It's like the computer is not remembering what position the IAC was at once restarted correct? Do you think my computer could have a problem? And valve cover gaskets are new due to having a leak like last month.
