I ported my own LS2 TB and I have ZERO codes

Stock un-ported on the LEFT, and home port on the RIGHT:

Its tough to get a good picture of the port job. The shiney finish makes an optical illusion

Ported TB mounted.

how much is a gas pedal assembly and where can I get the whole set of parts I need to replace...seems like the cheaper option....and if it is the throttle body then I guess I'll buy a new ported one.

my issue turned out to be the brown TB wire at the ECU was shorting and would make the reduced engine power mode come on. tuner ran a new wire and its been fine since.

what codes did your car throw? i want to make sure i dont replace an entire TB if it isnt needed. these are the codes my car threw at me

P2135ATPS 1-2 Correlation
P2176A Min throttle position not learned

Any ideas what those could lead to?

Just to bring resolution to this thread:

TPS sensor issue can be caused by buildup of gunk in the throttle body.
30min project, wipe it down slap it in and there's a good chance your car'll drive like new again.

I have been throwing the P2135 code intermittently for awhile and the P2119 came yesterday. Either way, I removed the TB cleaned it and put it back in and drove around the block. Cars run fine and no CEL' s on in the dash. I would be ecstatic if the solves the problem in lieu of a $330 or Throttle body.

Inspect your TB connector the 6 pin plug. The low voltage wire I think throws the 222 code do look at schematics to see which one it is. They can wear out get loose over time depending on the situation. ALso make sure it is snug on there. They have a locking clip.
