Have a 94 Toyota 4x4 22R engine. When I'm idling the engine wants to rev up and down. I've replaced the idle positioning sensor and that didn't seem to help. Any ideas?

I had the same problem with my old 91 4x4. I replaced the idle position sensor like the shop I had it at suggested. It didn't need it.:disappoin I finally got frustrated and played with it myself. I adjusted the idle adjustment screw on top of the throttle body and changed the position of the sensor untill I found a happy medium and it was fine after that. took some time but it ran for a few years without any more trouble.

No problem I am actually gonna try it again on a freinds truck sometime next week. He has a 92 with the same problem. It's a pain but it worked on my truck.
