TPS install help
I'm a quarter of the way through replacing the throttle positioning sensor.
Its attached in some way underneath the throttle body, how do I pop that end off?
Thanks, Jon

I wanted to avoid messing with the throttle body but I guess I'm gonna have to.
You took the entire throttle body off? Unplug/disconnect everything or just get it in position to get at the screws?

I appreciate the help, I'm about to run back out to the truck to see if I can get at the screws with my flexible ratcheting screwdriver (tool donation from the granddad, been itching to try it out)

Oh and how hard was it to adjust to get the proper voltage? I just found the section in the haynes manual and gave it a quick read through.

Check the operation with a ohm meter (or volt meter) before reinstalling.
Use a small pair of vice grips to get the screws out or you will round them out.

Help!!!!
Alright so 10 minutes into the test drive CEL pops up, truck starts to shift badly so I pull over into a parking lot and pull codes.
Get 123 and 998
TPS voltage high and something about the engine running in some kind of protection mode which is kind of scary
Let the truck sit for a minute and the CEL goes off, I get stuff done I need to. Leaving the parking lot of Wal-mart (yea i know but it was inevitable), truck starts fine, but almost seems to die like the engine wasn't getting enough gas. Back the truck up and put it gear, CEL is back on, go 50 ft. CEL goes off for the 8 minute drive home until I get to my road and start up it (mile long up hill gravel).
Towards the top of the road, CEL comes back on, truck seems to want to die give it more gas, and I get it to my house.
WTF is going on

Check your voltage at TPS, it should be 0.9 VDC closed throttle and 4.5 VDC WOT.
Look at this link.

Where did you buy the sensor at?

Got it in and good. Apparently changing the TPS so the cables faced outwards (towards the TB intakes) helped out a ton. Checked everything with the Volt-ohmmeter as best I could in a downpour under a jury-rigged tarp so I think it'll be alright. I'll double check when I get a chance.
There is a lot of difference in my skinny pedal. It seems to be more resistant and not so lose feeling.
Unfortunately, that didn't solve the problem of my truck's jerking/bucking like its not getting gas for a 1/4 second at a time.
