Sam, he said "If I let off the accelerator the car would idle fine, but as soon as I tried to accelerate the car sounded like it was about to back fire and then it would stop." I'm just saying that a really weak spark can cause these exact symptoms. Also, he already replaced everything in the fuel system including the carburetor and still has the same symptoms. BTW, mine displayed the exact same symptoms before it would stop.
Also, Batman13, pull your coil wire and crank the engine to see what your spark looks like. It should have some blue in it. Completely orange is an indication of a weak coil.
