Yeah, I don't get that at all. It really *shouldn't* be doing that. Is it possible there is a short in that connector, and it makes contact when unplugged? Or something equally as silly? The PCM sees the correct reading for the TPS, at least, most of the time....... That's a real puzzler.

 

I just desoldered the wire right of the PCM and its reading 5.098

 

If you unplug that connector, do you get continuity between those two wires? (unplugged at both ends.)

 

I just check it and there isn't

 

Failing PCM?

 

maybe, I just checked the alternator its putting out 14.3 volts. The engine lite if off again

 

You have an intermittent problem..... that's gonna be fun to find.
