If the ignition is alright, assuming the plug wires are on properly(1 & 3 wires are reversed on the cap, wire/cylinder 3 is in front, followed by 1 and lastly 5), take a look at the fuel system. Put a fuel pressure guage on it and see what your pressure is. Make sure its to spec and not low. If its low, even by only a few pounds, it can cause problems. lastly at this point, check for codes and see what comes up.

Oh and welcome to AF!
