TPS adjustment settings?
Does anyone know what the TPS settings are and what wires do you use to read them?

I'm doing this off the top of my head.
There are 3 wires to the TPS sensor. gray is your 5v reference wire black is the sensor ground blue is the sensor signal wire to the ecm If you back probe the blue wire( with a DVM to ground) with the key on/engine off, you should get a reading between .38 and .42 volts. That is the proper voltage at closed throttle.
