Thanks for that. If that is the case then how is ACDelco also claiming to be the manuf?
Since the TPS Pedal Assembly and TB appear to be related and talk to each other or both to the ECM about what is going on, then I'd lean towards them both needing to be of the same manuf to eliminate potential issues.
If they really are different, I'm wondering if that is what's causing everyone's p2127 that I find.
acdelco is a "licensed" brand, often made by someone else. you might be surprised how many "brands" come out of the same machine.
that is not to say that it is the case always but if you do a little digging/research you discover whats under the wrapper for everything made.
sometimes what happens is they just change the outer die with the name stamped on it for "licensing" or name branding and then turn around make there own brand name die.
or one brand name may require "tighter tolerance" which slows the machine down so it cost's more to produce
I sell on ebay for a living and have since ebay started in the late 90's, I sell pretty much anything I can get my hands on for a good price, sometimes the things I get do not work or need repairs, in trying to "locate" parts or ways to fix these random things I often find that the product label is just a label and who actually made the product is someone else.
without doing a deep dive into this another thing that happens is companys buy other companys and change the name or assume production under a new name this happens a lot
and some companys make the same product with different names or outside appearance so they gain a larger market share, one product 'name" or "brand" may be a big hit and they make lots of money on it and may even charge more because of it, yet still have the market for the cheaper no-name brand but they are the same dang thing.......underneath.

This really sucks. Picked up the replacement and installed. Idled at the typical RPMs but ran extremely rough and threw different codes triggering limp mode, stabilize and traction lights, etc.
Ran 3 minutes, waited 1 min and then retried with the same effect. Stopped the relearn process before it tore up the flailing engine.
I'm pissed. Going to return it and try the Hitachi model.
This ACDelco replacement had scratches and prints on the butterfly. Even though they say new, I think they just keep regurgitating the same crap over and over again.

Put the Old Original back in and now it's acting up for even that one.
Got the Hitachi and it does not have the GM stamp on it like the others but it looks much nicer and was packaged much better.
Even after sitting over the weekend with the battery unplugged (which also allowed a thief to enter my vehicle), it's doing the same thing with the Hitachi as with the others. Did the 3-1-3-1-3 run/stop
I'm assuming I need a hard Throttle Reset with a Tech 2.
It now has a weird sequence. Start it up and idles fine at ~700 rpm. Put it in drive and its okay. Just tap the gas and it takes off and will easily get you up to 25mph going up hill. Put in neutral or park and it idles at 3k and never goes back to normal. Shut it off, and start again, it's back to ~700 rpm.
Wish I never owned this vehicle. It's been a constant headache with the cracked dash, paint peeling, door handles busting, and leaking radiator.
Will the Tech2 clones work with a '98 Jeep Chrysler 4.0 PCM as well? Would be nice as that is what I swapped into my '84 CJ7.
