IAC Wiring issue
Hey guys I have a weird question.I was trying to check for codes last night by doing the whole paper clip in the A and B ports last night and a strange thing happened.My IAC valve came on.It was just buzzing like crazy,I don't think this is normal.Do you guys think I might have a short somewhere?

lol it's supposed to do that when you use the paper clip and read the codes.. it extends the IAC all the way out so you can set min idle.
