Hey @cruiser54, It been a while. Remember me? I wrote an addendum to your c101 delete.
Anyway, My air filter was saturated with oil and the engine bay was filthy. I took her to the car wash and thoroughly cleaned it. Then I did an oil change and added one of those cheap oil catch cans. I also updated the headlights to LED. Installed the relays years ago. Everything was working fine for a couple of weeks. Drove it exclusively during that time. A couple of days ago I had new tires installed. When it came back from the tire shop it started fast idle. What? I'm assuming it's just a coincidence, but maybe the that guys bumped a vacuum hose. I unplugged the TPS and the idle dropped to normal. Plugged it back in and it held. Turn her off and back on, fast idle again.
I'm planning on doing a smoke test to eliminate a vacuum leak. Tempted to remove the TB for a good clean and maybe just replace the TPS. Neither have been done in over 10 years.
Where would you start? Why do you think it started after a tire change?
Appreciate you, you are my jeep hero.
Dave
