So I replaced my TPS, to removed the TB and cleaned it up. I did not remove any of the springs. It was dirty behind the plates. Got that all cleaned up. Cleaned inside the IAC area. IAC is new 2 months ago. New silicon vacuum lines that go behind the IAC. New coolant hoses that leads to TB on the side and bottom. Cleaned up upper intake manifold as far as my hand could reach. INstalled a new TPS

Now I'm idling high at gear (at a stop light) and on P. I can move forward without any pressure on the accelerator when on drive.

This makes sense since more air, will give me more combustion. The TPS I got is the non-adjustable Motorola but it kinda moves a little, maybe about a 1mm or so. I can't take an accurate reading right now using the paper clip method.

I tried removing the battery for a few minutes to have the computer relearn.

Anything else I should look into?

You need to verify the voltage on the TPS before moving on to anything else. If that's good, what PCV valve are you using? Mine had a high idle using an Oreilly valve but as soon as I installed the Motorcraft valve it went down and smoothed out.

Thanks, I'm still learning how to back probe and/or piercing method. I'm using a paper clip right now and I can't get a good reading. It reads super low. So I'm sure my testing is questionable.

I'm also pretty sure I'm probing the correct wire. According to this:

I'm to test the black wire with the red lead and black to battery ground. I'm getting .3 all the time so I think I'm not probing enough.

I did not replace the PCV valve.
