7mgte hesitation *videos* help me

even if it was knocking it would not explain the cracked throttle and accelerating.

I didn't have a chance to really look this over before. A couple things I'd look at are the fuel pump relay and resistor pack, try an alternate ECU, try an alternate AFM. Is the fuel pressure up VSV connected, functional and properly routed?

I didn't recognize a wideband in you gauge set there. If you have access to one log it or at least make a video so we can see what's going on when it bogs.

Did you test the TPS signal at the ECU as I mentioned? What about the AFM (honestly I'd just try to borrow a known good one as I don't expect you have the equipment and documentation to test it copletely).

bad wiring from the tps to the ecu. ran new wires from the tps to the afm/eng temp sensor and ecu. fixed the problem
