Tp % is off ??? My 98 Z28 is scanning 14.5% tp at closed throttle. I checked the 5 volt refer with a multimeter and its good, ground is good, and output to the pcm is .5 volts and scanning 5 volts. Am I missing something here??? Can the scaling be changed in the tune??? What is up? I just want to clear this up before basing a tune on bad info. Thanks

unplug tps
turn car to ON, don't start it
wait about 30 seconds
turn car off
plug tps back in
turn car back ON
scan for new tps reading
profit
If the reading is still too high after that. You will need to adjust the idle screw some to bring it down. Everytime you adjust the screw, you need to do the procedure above.
turn car to ON, don't start it

plug tps back in

hmm, this might help me with my car. The TPS seems to be reading wrong as it is a different TPS than what came stock on my v6. Thanks for the procedure I will try it.
BTW, I know I am digging up an old thread
