well i know on my LS1 it started idling real high, shifting real shitty, and the traction control was acting all kinds of fucked up.

well on my lt1 i have to pat the gas in order for it to start or else it will just turn over and over (hot or cold)

Just ask it how its doing.

Could use a scan tool or use a multi meter and measure voltage

Only for sure way is to have somebody with a fast digital lab 'scope sweep it several times and watch the graph for spikes. Scan tools and ohm meters are too slow to catch the wiper going over a dead spot on the resistor. Can't tell you how many cars I fixed like that when other shops declared the TPS OK with a scan tool or ohm meter. Neither display data real time, they just show you "snap shots", and seldom catch anything. May look "real time" to you, but a sharp electronics guy will tell you digital meters are not.
Do NOT hook an analog volt/ohm meter to your computer! Any meter MUST have ten mega-ohm impedance. Not all do. Lower impedance meters pull too much current and can damage the ECM/PCM.
You likely don't have a scope like that (expensive) so borrowing the TPS off a good running vehicle, or buying a new TPS might be best.
Hope this helps.

Thanks for the info!! just another side note when i ran the snap on scan tool it show everything to be ok. So i am just going to buy one or try another one thanks guys for the help
