I have a question, when you hit the gas and the engine balks what happens to the tachometer? rpm needle falls to zero immediately or the needle stumbles downward?

when were your spark plugs changed? and the wires - have you checked them with a volt/ohm-meter for resistance.

Is your car running the original battery?

After you swapped AMM did you disconnect the battery in an attempt to clear codes/CEL light?

Also check for a vacuum leak around the intake; throttle body, manifold.

Fuel injection - you need a manual to diagnose that, but I would do new spark plugs and wires, and if that didn't work would check the fuel injection starting at the fuel filter.
