What would cause my car to buck while driving? Can’t get codes will not link up to scanner its a obd2 plug. I replaced tps,mass air flow sensor,idle air flow sensor,plugs and wires,coil packs,crank sensor. cam sensor. checked fuel pressure it ok. replaced fuel filter. Could it be with the transmission?

Yes it could. You replaced a bunch of things… did you check the engine’s compression?

The ECU may be failing. Electronic components have a finite life and yours are right there.
