Finally got a new re machined cylinder head on my 4.2L L6 with the help of my friend I don't think I ever want to do that again! What crazy person designed this engine???? OK, done gripping to the problems.
05 trailblazer 4.2L EXt
New - MAP sensor. Oil Pump, Belt, Plugs, Coils, Fuel Injectors, Fuel Pump, Fuel Pump pressure Sensor, Water Pump, Timing Chain, Re-machined - Cylinder head with new values, springs and rocker arms, Seals, head gaskets, exhaust manifold gasket, intake manifold gaskets.all seals plus etc. Re-did the complete motor but the pistons and block they were OK! Had 4 bad values millage 192K on motor.
- Was getting a P2135 and P0651 Due to my low budget and my cancer treatment I went to the junk yard got a used throttle body form 05 trailblazer with 86K that was a rollover wreck for $22.
Now the vehicle runs better but if I press the pedal down to give it gas for a fast acceleration from 20 mph to 50 mph if hesitates 3 - 4 times or more but will get up to speed. Never took it on the highway yet so 50 mph is the max speed I tested.

Should I change the gas pedal sensor also?
The electric fan clutch must be working OK never over heated in 96 Degree F outside temperature driving for 30 minutes.
I know the gas pedal, throttle body, and electric fan clutch and maybe the gas tank pressure sensor all run on the the 5 volt agree and disagree reference.
My cheesy reader does not live read voltage ref.
Also disconnected the tail pipe in front of the catalytic converter still no change just more noise
Currently throwing no error codes at all and engine light stays off?
Any suggestion to try next? Or test?
-=-=-
UPDATE:
I went out to the trailblazer to get a my manual and tried to start it.
Would not start and throw a P2136 P651 P2135 codes. Cleared the codes.
Just wondering I decided to unplug the electric fan clutch.
The trailblazer started and throw the P0651 code which I know it would.
This is the voltage B ref per my cheap old reader.
Could this be caused be the fan clutch and still cool the vehicle in 97 F heat?

Thank you in advance!
