I understand what i have to do to adjust and reset it. The only thing im not sure on is testing it and what setting my multimeter should be on when testing it.

Also, dont you just jam the positive pole behind the connecter (middle wire) and ground to a screw?

I got 0.57 at the V(3 dotson top, straight line)- 20 setting but just wanna make sure thats the right one.

Thanks

Check your TPS voltage before doing this modification as none of the factory sensors are calibrated the same. We've seen ranges from .3v-.7v...from the factory. Connect a Digital Volt Meter to the middle terminal on the TPS sensor (with the harness connected and the Key-ON/Engine-OFF). If it's close to .7v...leave it alone.

(1) Remove your TPS Sensor from the vehicle (Located on the drivers side of the throttle body - 3-Wire Connector)
(2) Put the TPS into a vice and drill the two brass inserts out of the casing with a 1/4" or 7/32" drill bit (drill from the back of the sensor...not the front). You'll need to push on the drill as it will only spin the inserts...once they're heated up enough, they'll pop right out.
(3) Clean up the holes with either the drill or (preferred) a small round file.
(4) Reinstall the TPS Sensor on the throttle body. You'll need two small washers on the screws as the holes are now bigger than the screw head. Leave it slightly loose as you're going to have to set the initial Key ON/Engine OFF Voltage before starting the engine.
(5) Reconnect the TPS sensor harness and connect a Digital Volt Meter to the middle terminal on the TPS Sensor (you can poke through the weather-proof connector).
(6) Turn the ignition key ON but do NOT start the engine.
(7) Set the initial voltage (by turning it with your fingers) on the TPS at about .7 volts. (Optimum range is from .7 - .75 volts)
(8) Tighten down the TPS screws and check the voltage one more time (yes...it can move slightly when tightening it down)
(9) Start the engine but do NOT step on the accelerator pedal...let the computer learn the new initial voltage setting.
(10) Turn the engine off and close the hood...drive away of you want...your throttle response should be much more precise now
