TPS gone haywire.
This should be fun. I've been having an issue with my car where now and then while driving the SES comes on and it feels like moving the throttle does nothing. Today I confirmed it. I hooked up a snapon scanner while driving to work and saw when the SES came on my TPS suddenly went from 0.54 at an idle position to 0.30 and full throttle was no longer 4.8v it was now 2.3v. Oh goodie!!! I just hope its the sensor and not a break in the reference wire or something that I have to trace back.

One way to find out....replace it.
Hope that is all it is. PLay with it a little with probes right on the sensor itself. See if it moves linearly. If it doesn't its definately the sensor. But if its itermittant, you might as well just replace the unit and hope it cures it.

When I get home I'll toss the GM one back on. This one is a cheapo $15 Wells unit I got at autozone one day when I thought it was bad, but ended up being an O2 sensor that day. I never put the GM one back on.

The wells one I had did the same thing all of a sudden, just replaced it with another wells because I don't think $60 from the dealer was all that fair. I laughed at them and asked you sure you looked up the correct part.
