Developed a strange high idle conveniently after I spent some time on Sunday checking the resistance on the TPS pins per the FSM. I circled around and around again trying to figure out what I had done to cause this issue and I kept coming up with a blank. Finally I decided to remove the TPS itself to inspect it which turned into a huge pain in the ass since you either have to remove the throttle body or the IACV to access the TPS. I opted to unbolt the IACV and pull it away from the manifold while it was still attached to it's hoses and of course ended up slightly tearing the ancient gasket in the process. When I finally got the TPS off, I could tell immediately that it was gummed up and not returning to it's "home" position. After going to the dealership to order and new IACV gasket and TPS, I realized that the TPS may actually not be bad so I sprayed a small amount of penetrating oil inside and spun it back and forth until it freed up. Now after reinstalling the TPS (and the IACV using the ripped gasket in the interim) the trucks idle has settled back down although a little lower than I would like it.
The next time this comes up I have decided that I will either take the throttle body off and make adjusting the TPS easier on myself, or hire a child to climb in the engine bay to put the thickness gauges on the throttle stop.....what a nightmare!!!!
