Can't beat that deal. be sure to disconnect the battery before swapping it out. You also should have a digital multimeter so you can verify TPS voltage is between 1.19 and 1.31 volts (key on/engine off).

I swapped mine without the battery and it works ok. Does the PCM
do any calibrating for the TPS?
