TPS Reset Not Working Please Help! So I've done the TPS reset procedure that's featured in this forum four times and every time my scanner still reads 2% throttle at the end. Has anyone else had trouble doing this? I'm just trying to smooth my idle out and I'm using the Torque OBD app.
Edit: Every time I shift into drive the car surges against the brakes so I'm assuming my scanner isn't the problem.

IAC Relearn Procedure
If you are having idle issues you may need to reset your Idle Air Control (IAC) and TPS, do this before you start drilling holes in your throttle body (TB) blade. I have used this procedure on some huge cammed cars and it worked.
1) Monitor your IAC, Idle Speed, throttle position voltage and your throttle position %.
2) With the key in the ON position, adjust your TB set screw until your throttle position is 2%.
3) Turn your key to the OFF position.
4) Unplug your Throttle Position Sensor (TPS) and IAC.
5) Turn your key to the ON position for a few seconds, and then OFF again.
6) Plug in the TPS and IAC and then turn your key to the ON position and restart logging. Your throttle position will now be reset to 0 degrees and about .45-.55 volts.
7) Start your engine, your IAC should be 40-60 for a cammed engine.
If you are not at your desired IAC position, redo the above procedures in smaller increments.
