1995 Camaro with 5.7. Car idles high and does not recognize the TPS. Brand new TPS just put in.
My 1995 camaro just started to idle to high what could it be
Check for vacuum leaks
SOUNDS LIKE AN INJECTOR FAILED AND THE COMPUTER ATTEMPTED TO COMPENSATE
I had wired the tps backward and it idled at 3k just because it thought i was at full throttle. a short in the wires might be causing something similar. also incorrect voltage from other sensors like coolant temp can cause it to idle high.
What about if u check the signal going to the ECM with the full throttle it should be 5 volts, a good TPS should be between 4.5 & 5 VDC but u will have to check the wire end that gets into the ECM.

ok if it doesnt have the volts needed and its a new tps then what should i do?
very high idle 2500 and high voltage to the tps. We started it and moved it out, left it running and when we walked out the idle was thru the roof
