Didn't recognize the name in the email. Sorry. I was in a hurry then, too. Yes, your TPS sounds bad. The rheostat is worn. Testing it for resistance is the best way to check it, and your results mean that the rheostat has several worn spots on it. The engine should run fine until it hits one of the bad spots. Then, the ECM doesn't know what's going on. Replace it with a new one, but make sure you reset the ECM afterwards (disconnect neg bat cable, turn on headlight switch for 10 minutes to drain capacitors, reattach bat cable), and then do a re-learn for the ECM:
idle @ 1000 rpm for 1 minute.
key off for 10 seconds.
idle @ 1000 rpm for 1 minute w/ a/c on high, headlights on high, etc.
key off for 10 seconds.
idle @ 2000 rpm for 1 minute.
key off for 10 seconds.
idle @ 2000 rpm for 1 minute w/ a/c on high, headlights on high, etc.
key off for 10 seconds.
test drive.
Take care,
~Chris
