How To Check Tps For Correctness? After installing my shaner T/B last week, my idle is much higher now. It goes up to 13-1400rpm, and very slowly comes back to around 850. Like in stop-n-go traffic,when I push the clutch in ,idle goes way up,then very slowly comes back down. Any info on how to check the tps with a meter, or links on this how to, possible a relearn?thanks

Sure, you can do that. I had a Haynes manual for my LT1 that gave the proper voltage readings (5V max, I think for that sensor). You just turn the key on, put your test leads on the input wires to the TPS and flip the throttle blade to see the output range.

The TPS should be NO higher than 4.64 VDC at WOT because the manual says the DTC sets at 4.65 VDC. The manual also says the closed throttle value should be NEAR 0.6 VDC.
