Need some help here...

[HDGMC]

So I went to put on a new throttle body and was not happy with it. The truck idled all over the place...any where from 600 to 2500 rpm. Every time I touched the gas pedal, it came to idle at a different rpm. Keep in mind this is a 2006 RC with 4000 miles on it. Anyway I put my stock throttle body back on and same thing. Am I correct in assuming that I need to go buy a new TPS?...really...after 4000 miles? Is there somebody out there that can shed some light on this. And yes I had the TPS indexed correctly. Are the bolts that sensative to torque? Should I bust out my torque wrench? Does the truck need to learn something since I unplugged the sensor? Thanks for any input.

if it does it with the stock one back on, might be a vacuum leak.

Spray some WD-40 on the spring. That worked for me.

My spring was sticking because it had polish stuff in it. maybe you have dirt in it.

make sure first the vaccum line under the tb is connected and not leaking
