Well, I must have Elmer Fudd Syndrome, I've R&Red it many times and never had to relearn anything, but maybe that's why my car doesn't go into boost what's the procedure?

91parkave; did you go through the same thing?

Not so much an issue with the 3800, though I guess it could never hurt to see if a learn is able to be done.Originally Posted by J57ltr
But basically any Gen 4 V8 from GM, so 07+ motor but included in the LS4 that came out in 2005 are known for throttle body issue have cleaning them. I've cleaned many and not had and issue but I never touched the throttle blade.

I did touch the throttle blade. It had carbon build up on the edge.

When I first got my car I pulled the TB off to clean it, opened the butterfly by hand and cleaned the crap out of it. Didn't have any issues after reinstalling it so I don't think that's the issue. There Re several threads that say it's no big deal and that the FSM has no mention of the 3.8 or 5.3 for a relearn. FFDP was the author of a couple.

It says do not perform this procedure if DTCs are set. Should I clear DTCs first and then do it or is that not how it works?

What dtc do you have
06-24-2015
At first p0420 and p0121. Then I cleared codes but p0420 came back.

Just perform the procedure

Did you preform the procedure and how did it go?

No. I got a different app called car gauge pro with which you're suppose to be able to perform an idle relearn but I haven't figured out how yet.
It looks like my idle is slowly getting closer to where it's suppose to be. But when I'm driving and let go off the gas to coast to a red light, the rpm's still go down very slowly.
According to torque pro my vacuum at idle with car in neutral is a steady 18inHg. When I put it in drive it goes down to 14-15.
