I have replaced wires rotary button and distributor cap replaced the coil replace the air filter replaced the factory AC iridium coated plugs. Motor runs good tac sits smooth while idling. Put on only when I'm driving and get ready to pass someone like accelerator to the floor I get to downshift and then I get a large pop like there's a complete dead cylinder and then it'll pick back up again and it's fine.

How can I test to see if it is the fuel pump falling under a load? And can I test the ignition control module?.....how
