I'm about 90% certain that my recent idle problems are from a bad tps. Has anyone else had this problem? It makes sense to me since a lot of time is spent idling for warm up and cooling down. It can't keep a steady afr, it wants to go to low 13s, sometimes even to 12s, and then jumps up to high 16s. Twice it stalled on me. My next step is to replace it and the seals on the throttle body. Just need to find a good one for sale. Any opinions on this topic are gladly welcome if you think it might be something else.
