Hey Im in the process of swapping a 99 4runner 4x4 auto 3.4l engine into a 1998 4runner w/ 3.4l manual. I guess I should say swapped. Does anyone know what sensors need to be switched over? I cant seem to find any info on cam sensor, crank sensor, iacv or temp sensor. The TPS are the same part number from what Ive found. Any help would be appreciated as the high idle is driving me nuts.

 

The sensors should all be the same. I put a 99 into my 98, although they are both AT, not MT. AFAIK, the sensors are the same.

After I did my swap, I had a high idle that was being caused by a gunked TPS. After taking that apart and giving it a good cleaning with some brake cleaner, she fired right up and idle dropped to around 750 or 800. You should give the TPS/MAF/TB a cleaning and see if that helps. Try the cheap fix first.
