I just installed rebuilt fuel injectors, rotor, distributor cap, spark plugs with wires and the engine still has a major miss fire. What should I check out next?

Possibilities

Have you checked the spark plug wires to make sure you have the correct firing order. Also does your distributor have the extra points in the lower part of your distributor. If there are wires going to your distributor about the 8 oclcock position when you are standing in the front of the car looking down and the rear of the distriutor is 12 oclock... Jim

Timing could also cause a miss and sometimes a backfire under hard throttle.
