Just replaced my Head gaskets, Now some idle issues.
The biggest issue I am having is high idle. My vehicle idles between 1700-2500 in part and neutral. When in drive or any other "moving" gear it falls to 750. What could case this?
When doing the HG's did you remove the IACV or TPS and mess with them? possibly your two culprits. Are you having any other symptoms such as hard start or dying after it heats up?
I would say two choices at this time. 1) Let it go for a few drive cycles and see if it resets itself 2) take it somewhere with testbook and have it reset.
