Thanks for some insight on this. It has been something I have been picking at for awhile. Being it's my daily driver and mostly used on highway I just deal with it. If I bust out the old multimeter what are some values I should be looking for on each wire?

Where do I find relearning procedure for the car? I want to fully reset pcm. I am also looking at buying a sct tuner as well. Has anyone had success in dialing in a nice idle with that tuner? Thinking it might be last resort after tps.

For relearning, disconnect battery for a while then to speed up the process when you first fire it up let it idle until it drops to a normal low idle.

Forget the multimeter, you need to look at reported throttle position with a scan tool.

And an SCT flasher/scanner is NOT the way to do it. Can't adjust idle/idle quality that way on your own. And a tuner can't fix it either while there's still a possible mechanical issue.

What kind of scan tool should I be using, I am trying to do this on a budget. Bringing it in to the dealership in town is a no go. They have had no success in resolving this issue. They say the surging is normal. Can I install a program and get a cable to get reading on this?

I was also looking at getting sct tuner for future upgrades, was not sure if it could increase idle speed a little bit, or if it would take care of bouncing idle.

Get the Chinese clone Ford IDS and VCM from eBay. It's Ford's own dealer scan tool. Just the hardware is a knock-off but it works fine.

It's called VCX Nano. Just make sure you get the Ford/Mazda one.
