Hey y'all,

I had my PCM replaced after I did a bunch of TB work on my own for a high idle issue (IAC valve, PCV, cleaned throttle body, new MAF tube and sensor). The dealership installed the new PCM but when I picked it up it had the P0507 code on the dash already.

Should I... Adjust the throttle set screw? Perform an idle relearn? Replace my IAC Valve again? Take it to the shop and get various pressure sensors tested? Check and replace any faulty fuses?
