Default Code po507

Check engine light came on, took it to autozone and had it scanned. The printout said idle speed higher or lower than expected. It idles around 600 rpm. Can't find a vacum leak, iac is new,throttle body is clean. Possibly poor electrical connection? The car runs great, the only problem I have is sometimes if I drive the car and turn it off and start the car and drive for about a half block the motor runs like crap and then runs fine. Mods are in my sig. any ideas? Thanks

Idle is a bit low.

Did you perform the idle relearn after installing the IAC?

Cycle the A/C on and off intermittently for 30 seconds each time. If it's an automatic, do it in all combinations of drive and park each way.

Thanks for the reply.

What should the idle be?

Did not perform the idle relearn. The light was on before and after the new IAC.

Car does not have a/c. Thanks again
