Hi, I've had high idle problems with my 1992 toyota pickup ever since I bought it. I put in a reconditioned 22-RE engine a few weeks ago and hoped that the idle would be fixed, but it was not.
As of now, when I start the engine, it immediately rev's to about 2000 rpm's, but after the engine is warm, it settles to about 900 rpms. The idle is consistant and slowly goes down as the engine temperature goes up.
Is there anything i could do to fix this? - A friend suggested I replace a chip of some kind that controlled the mix of air and gas, but I'm not sure about that
