hi all quick question, when the iac valve goes bad besides the high idle on start up and rough idle as i have, does the check engine lite comes on? thanks ...

Pull the codes and see what they say. My CEL didnt come on with bad IAC. Do you have a CEL?

There are codes for IAC but i dont know about a check engine light!

yes i do have a cel......comes on when it revs high and sometimes after driving for 15mins. when it revs high the cel blinks 3or4 times and it stays on after 15 mis of driving. when i start up sometimes it don't rev high and the cel don't come on
