Default 1993 Ranger 2.3 problems.

I've had this truck for two weeks now. When I fist got it, it revved high between gears while shifting, (Manual). I cleaned the Idle Air Control valve, the MAF Sensor and the Throttle Body. It seemed to fix the problem. After a week it all of a sudden started running rough. The morning was fine but that afternoon it started running rough and seem to loose power. I pulled codes,
KOEO 157, 327, 334 and 543. KOER 538. But I'm not sure when those codes were stored. I've checked ground wires and they seem fine. I cleared the codes, and now have no codes except the 538 one. Maybe I need to drive it for a bit to get codes. My question is, where do I start. Note: the engine I believe is a junkyard motor out of a mustang. 93 2.3l.

I had the same thing. In thinking throttle position sensor. I've had multiple Rangers and have lots of parts. I pulled the receptacle off the throttle body and I cut the plug off of another harness. The TPS was older for my 93 than the 97 I took it off of. That's why I had to change the plug as well. But it sounds like that might be your problem.
