First of, pizza guy; thanks for the help.
For sure this has been subject to anyone's best guess, and nobody has guessed right so far.
This new mechanic is an old school guy, and unlike the last guy, he took my list of all things replaced and started away from it. The last guy after Matt said it was the RCM, , which was the first thing I had redone by Brian lol. then he said maybe the the crank sensor ( also replaced before bringing it to him ) and finally, he admitted he not only didn't have a clue, but didn't want to bother looking into it.
So this new guy who works on performance cars is pretty locked in on the Throttle body, so I ordered the upgrade from Needswings.
BTW He also mentioned the attaching connections seem brittle, so I'm wondering were to get them? lmk if you have an idea on that
