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

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
