If the TPS voltage remains in range, (above .5 volts and below 5.0 volts), a DTC will not be set. The processor does not classify voltage drops or spikes that are within range as a fault. It's up to the technician to determine if the spikes are abnormal. Your first test showed voltage drops, and that's a problem. Your second test had acceptable results, much like your 200 miles of trouble free driving. The TPS is faulty, replace it. Cross your fingers and hope that's the only problem.

For those who had been following this thread, the TPS does appear to have been the problem. A couple of hundred more miles and the problem seems a thing of the past, but it ran well previously then crapped out on me. Hopefully, this thread has come to an end. Thanks for the help.

Knock wood it's fixed. Intermittents can be a real bear at times, but it looks as though you've pinned this one down. Persistance pays off. I don't want to be premature but, glad I could help. If it acts up again, post back.
