03 Gp GT 109K. My check engine light recently came on after idling at 2k. I hooked it up and got the code P0507 I believe it was. Anyways i looked it up on shop key and it came up under my IAC valve (Idle Air Control). So i took it out, cleaned it, followed a flow chart, making sure all vacuum lines were good, etc. But i just haven't been able to find much info anywhere. I bought a brand new one, adjusted it to manual specks 1 1/8 inch from gasket mount to the top of the pindle, put it on correctly, started her up and she was idling at 4kI took it down the road at 40mph because the manual said at that speed it resets itself. It didn't, took it off a couple times and tried adjusting it. Either it would idle so low it would hardly stay started or it would be around 3-4k. Put my old one back in and i was back to 2k idle (185F). I am stuck on what to do next, i have some free time today and hope to hear something back to get this fixed. Thank you for any help at all!
