Usually, but not always. There'* 2 TPS codes possible, and they won't always throw an SES light. I have experienced a TPS failure on my old 94 Suburban that did NOT throw a code though. A dead spot can do it, and it sounds like that'* possible on yours. Still could be any number of different things, which is why it'* important to check for codes.

Get your paperclip and get out there.

i have a little code reader thingy.....i can use that...waht code number will it throw...?

Will, can you post that pic? I was having weird running "problems" tonight...kinda similar to CrazyDriver. But it would be good to know what the TPS is anyway.

Thanks Will.

whats the little round thing that seems to move up and down when starting and stuff....has a little metal piece that it moves on that goes up and down?

my car does that at stop signs and at red lights, and when ideling in park almost all the time.....new plugs, wires, fuel filter, air filter, and MAF sensor...and i run Red line injector cleaner and i use 91 octane....also i did a code scan with the paper clip and it is throwing nothing so whats up!?! im confused lol

Matt, I'd clean the TB if I were you. Remove it from the SC, remove the MAF, then clean it well with an intake safe cleaner and brushes. Toothbrush, pipe cleaners, acid brush, whatever it takes. Let it soak awhile, too.

no codes ...!!!

If you have a voltmeter (digital only!!!!), stick a paperclip down into the harness of the TPS so it contacts the DK Blue wire (centre I think) with the positive. Put the negative on ground. Turn on the ignition (do not start). The voltage reading should be about 0.36-0.42 or so. Slowly sweep open the throttle and observe the voltage rising. It should be smooth and proportional to the opening of the throttle. The max reading should be around 4 volts. It there is a flat spot the voltage will suddenly fluctuate at the same spot.

A faulty TPS will not ALWAYS set a code or SES light condition. USUALLY, but not always. Try the Canuck procedure. That'* what the service manual calls for when diagnosing these problems.

You guys still need the pic?

yes...pic good...lol...

update...drivin car today...was goin bout 45 comin up to 30 zone so i let off the gas...car wouldnt slow down after 40 it was like stuck on 1500 rpms...cruise wasnt on i checked it...car ran like that about .4 on the trip thing....then it went down....its weird...same thing you think?
