2008 Z71cleaning Throttle Body

[RV0244061]

hey guys, so i have a 2008 z71 5.3 silverado. lately i noticed that at the stop light i had a little shake. so i decided to clean my throttle body out. the truck has 44,750 miles and it had never been cleaned out untill yesterday. well the "shake" is gone... the thing now is that it "reved" up a little too much. when i turn it on it goes all the way to 2500-3000 rpms and then comes down to 1000 rpms. when driving it and slowing down for a stop, it has like this pull feel. almost like it doesn't want to stop. what do you guys think? is the truck trying to used to it and is this normal? i think maybe i should of put a new gasket and maybe there is a leak? what can i do to reset the tp sensor?please help out. i thank you in advance!

disconnect the battery for a few minutes and then reconnect & start the truck up, let it idle for a while.

 

stupid simple...but its where id start before digging in to gaskets and stuff

I just went through the same thing on my 2008. Just disconnect the battery for a few minutes, then drive the truck for a while. It took about 50 miles for the computer to relearn the idle. Works fine now.
