I hate when people spend money because there mis informed.. Ok not bragging but I think I'm the master with this. I had the same problem various times..
Chances are your oll TPS was good, the computer just forgot what base closed was. Unfortunately you HAVE to have adaptive values reset. Usually 1hr shop charge. Don't even bother trying anything else. Trust me I tried it all.. You drive without the TPS plugged In and then plugged it in.. Have to have it reset sorry

I want to ask you a couple of questions after reading this and your following post.
Are you 100% sure about the "advice" you are giving?
I see a relatively low number of posts from you and your advice is in direct contradition with some other members who have extensive knowledge about these vehicles from their own personal experiences, please ensure that when you do give advice that it is correct.
Can you provide the specific details to justify your position?

In my somewhat narrow experience, my D1 would not idle below 1700. When IACV replaced, computer would not "learn it" no matter which "dance steps" I tried from various forums. Ended up getting an ECU and an IACV from same donor vehicle. The practice of taking to shop for parameter reset is a valid one ( I was too cheap and too stupid). I don't think the CPU is reset by running with TPS off, but a TPS failure can make truck run bad and cut off at aboyt 1800 rpm. My base closed reads a little over 9% on the scanner for TPS position. Zero physical position may not be "zero" to the computer.

Do not for any reason remove TPS or unplug it unless its already broke..

YES IMMSURE AS TO WHAT IM SAYING! Go Messing around with it for no reason, maybe it will work after, maybe NOT. You'll be paying the dealer an hour.
As for me I have around 4 experiences with this. You can have a good TPS checked by Meyer or even better through obdII, but once the ecu detects DONETHING changed you'll be in fault mode and there is NOTHING YOU CAN DO, other than reset values.

Only other option besides reset is a junkyard ecu and matching TPS. Ask me how I know..

Danny, its true that a high idle can be due to the ECU being out of whack and needing to be reset. This cannot be done by the shade tree mechanic. You need fancy wahzoo computers.
High idle could be attributed to a great number of other things, but it could also be the base values needing reset.
