I have a new project I'm working on. Picked up a 92 regular cab 2.3l from a guy who said he put a new motor in it and transmission. Well, he was right. He sold it cause he can't figure out how to get it to run amongst other things. The thing is, from what I can tell. It has a MAF harness from 1991 and a Computer from 1990 (MOM2) also CA Emiss. I'm getting the standard codes saying it can't control Idle out of specs and the TPS sensor is out of range. It's running like it has a vacuum leak that I can't seem to find and my vacuum tester agrees. Sounds like it's coming from the throttle body. Yes, I've checked/changed all the hoses and going back out there to figure it out.
