Bad PCM?
Hey, guys. I have a '93 Explorer XLT that idles pretty lousy and the temp gauge fluctuates wildly. I did a voltage test both at most of the sensors and back at the PCM and all of the voltages are too high. I find it unlikely that I have a short on every one of those circuits so the only thing I can think of is that the PCM is crapping out. Any ideas what else I can check?

I have a 94 and replaced the PCM about 3 years ago because of an irratic idle. I didn't have the fluctuating temp gauge though. I believe I've read hear that a bad thermostat and/or bad temp sending unit can cause the engine to idle poorly.
