You guys are great, thanks for the info. I checked the throttle plate a half dozen times hoping to get it to stick, its free as it can get. When it acts up, the tps b is 29.8 %, while the command is 21%.I'll have to look at the fuel trim.
I will also have the throttle relearned and see what happens there. Thanks again guys

Ok, truck is fixed so I thought Id post in case someone else came across the same thing. I had my throttle relearned and everything went back to normal.(Thank you Silverado1SS89)
It was explained to me that as the throttle body gets dirty, the ecm makes adjustments. WHen the throttle body is cleaned, it is a sudden change and the ecm doesnt know what to do. He said it would readjust back to normal after 150-200 miles of driving since the GM electronics learn how to adjust settings based off of your driving habits. In short, if you clean your throttle body on a newer DBW GM, have access to a Tech 2 scanner that can aid in relearning the TPS or be prepared to make a 150 mile road trip. Thanks again guys

Cleaned the throttle body on a 07 Tahoe 5.3 now it gets high idle code and when you rev it up it will idle around 2-3 rpm. If you start it up and don't rev it it will idle at normal rpm but as soon as you rev it it will not come back down to idle. Tried relearning the idle with a tech2 didn't help. Tried a new throttle body same. Smoked the intake showed no sign of a vac leak. Fuel trims are normal. The Tahoe is all stock right over 100k. Any help appreciated.
