This has came back multiple times . I just tried ECU reset, relearn IDLE , from technosquare and I cant get CEL to blink .I have older sedan with old harness ECU .Will this procedure even work since its the old style. please I am in need of help with this issue and would like any advice

 

procedure works fine...you must use a stop watch to be accurate though

I always use a video on my cell phone and just use the time counter as my stop watch.

 

so then u have a stepchild ecu too i assume and you havent had a problem. I will try to reattempt this and see where it goes from here any more insight

 

P0507 Idle Speed Control System

I don't recommend for anyone but the dealership to clean the throttlebodies. They lose their calibration really easy when they are pushed open.
