5.8 high idle issue
Hey guys new to this form. I have been stumped on this high idle for a while now. I have replaced the tps sensor and the iac. It was idling at 2500-3000 rpms and wound not kick down. After I replaced the sensors it sits at 1200. I have checked for vacuum leaks can't find anything. Help asap would be much appreciated.

1) Did you reset the PCM after eplacing the sendors (leave the battery unplugged for at least 30 minutes)?
2) Did you test the voltage on the TPS after installing to be sure its within spec?
3) Do you have a Motorcraft PVC valve? Seems weird but I had some idles issues solved by just this alone!
