IAC and TPS remember, their married!

Hi there,

Remember that any time that you adjust the idle air screw, in or out, that you are also changing your TPS setting.

You must be able to read both of those settings while monkeying around with either.

Take some time and try to adjust screw and the idle TPS setting so that you end up with 0 IAC counts, while establishing an idle TPS of .46

This has worked very well for me, however every car is different, and you must be willing to spend some time tweaking YOUR specific combo.

In regards to the TPS setting, get your wide open TPS set to 4.80 or so, and then tighten the lower of the two screws on your TPS sensor. Then, using that lower screw as a Pivot point, you can loosen the top screw and move the sensor up or down to adjust your idle TPS setting while moving the IAC screw in and out. It'll take some time, but it will work by watching your numbers and just going back and forth with the Idle TPS and IAC settings.

Good luck!
