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?

sounds like a vaccuum leak :dunno:

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.
