So my SES light has been off on for the past 3 days. Today I went to autozone for a scan and it has a P0507 code (picture attached). Apparently my idle is high, but on the way home I checked it a few times, and it was in the 700-900 range. Is that high? I've noticed no difference in how my car runs. Is it possible that this could be caused by my CAI? It's an Injen CAI, I took some pictures of it because it looks pretty worn out- or is the CAI completely unrelated? I see that a lot of people reset the ECU, should I do that? Thanks

 

Intake could cause idle problems but so would other factors. If you have been successfully running a intake, then get a SES light, I suspect that it is NOT the intake.

 

It won't hurt to reset the ECU but it probably won't help either.

If you would have searched this very forum for P0507 you would have found this thread on the exact same problem...

I'd try the three re-learn procedures described there first.
