Blutooth scan tools?

What's the engine doing (fault codes), and what year / model is it in? I'm assuming it's a 3.6. You mention TPS, in plural. Knowing they are part of the throttle body, and not serviceable (by most); you just need to verify wire condition (via load testing them), and that signals are making it to the PCM. If so, it probably needs a throttle body replacement. Now, if your codes are along the lines of APP 1 and 2 - you are looking at the accelerator pedal. If you are dealing with correlation faults, you're going to need a scan tool capable of performing relearn task$$$.
