I replaced my IAC and TPS as well as all the gaskets and now my truck is idling higher than normal when I first start it up (around 1000rpms when it's cold... Temp outside is about 70) and when I shift it from drive into park my RPMs increase to about 900 then drop back down to about 600... Is this just because of the new parts, did I mess something up, or do I need to adjust something? Any help is appreciated!

 

Did you disconect your battery for at least 15min. or disconect both terrminals and touch them together to reset the computer? and then let it idle for a couple minutes for the computer to relearn the idle? just an idea

 

I have not yet but I was planning on trying that tonight
