Sounds like you've done everything you can regarding the IAC.

TPS reset requires you to use the pull down menu in the software, and activate the TPS reset utility. Not automatic by cycling the key. Once activated, you push down on the throttle pedal (or throttle linkage) twice, slowly, while the sensor calibrates as it ranges from min to max. Then you cycle the key.

As a check, you can push on the throttle linkage under the hood to seat against the idle screw while watching the display. The TPS value should not change. If there is mechanical slop in the linkage, or a poor return spring, you will see a change in TPS %- this is a problem. Make sure the TPS is rock solid at 0% at idle.

Are you talking about the terminator? Because instructions in the Sniper Stealth specifically state a TPS reset can be done with a recycle of the key. In fact when I was playing with the throttle screw and cranking it up while messing with the IAC, the TPS was at 3%. When I recycled the key it went back to zero.

I didn't realize you had a Sniper. OP has a Terminator, as do I. Sniper does the key cycle auto reset as you describe.

I kind of figured, I was asked to join the conversation. Although they do share much of the same tuning aspects and ideas in timing and fuel.
