Hi all, I replaced the TPS since I got an intermittent TPS code (can't rem. what it was) and it had 179,000 miles on it.

Now my idle is 2200 rpm in Park. Battery was disconnected for 40 min. and then ran it until warm (195 read on scan tool) but I still get the high idle. Everything is connected, no vacuum leaks.

I checked the throttle blade stop screw and it looks to be turned in all the way. I wonder if previous owners adjusted it. Can someone look at that theirs and see if it is all the way in?

Thanks!
