Well had to pull the blower back off working by yourself is no fun. Left all the water line and anything I could still hooked up. Now on to checking the sensor I have a new one for it.

OK now I am getting mad. three sensors and all show to be good. All show the same code Consecutively High. Plug is good and all wires are good. Anybody know what to do?????
Up date truck is done but not running right waiting on a new tune to get here. Thought I would post what the truck looks like. Right now it is high idle code put in a new one but it is still high 2300rpm. Checked for air leaks and could not find any.

Boy I hope the tune makes it today!! Never go ground again the wait is killing me.
OK Tune "3" and guess what a new code. PO1336 Still idling high 2500rpm. Checked for air leaks pumped 15psi to it and found no leaks. The truck has been done a mouth and have not put one mile on it. Not Happy right now not at all.
That code is normal, it's the pcm complaining about needing a ckp relearn, but that's not what's causing the idle issue.
Just to recap and keep those who don't know updated:
pcm 1: tuned what i was supposed to tune for
pcm 2: reloaded same tune just to be sure it wasn't a bad upload
pcm 3: completely different calibration just to be sure it wasn't the cal.
similar issues with all pcm's, so let me know if there's anything else you'd like to try.

just a thought- is your throttle blade closing completely? maybe it is hung open.
I could here air come out of it when I put air to the manifold. But it looked to be good.
With a good scan tool, you can check to see what commaned idle is, i know it's not 3000rpms, so since it's actually idling higher, see if it's cracked open a bit, even just a slight degree open will cause a high idle.
did you change the tb during this swap?
do you have another truck to swap out tb's with?

Same TB the other one is a wire one so that is no good. I will get back out there first thing and get a real close look at the TB. If it is open how would I adjust it?. I am open to anything.
