Stock 5.0? How do the spark plugs look? Adjustable or non adjustable fuel regulator.

STOCK 5.0 BUT HAS EAGLE RODS AND FORGED PISTONS, NONE ADJUSTABLE, SPARK PLUGS ARE NEW

Pony 5.0

If you still have the stock fuel pump or ignition coil, I would look there.

I HAVE A TWIN TURBO KIT ALSO SO I THINK I AM GOING TO GO WITH EITHER A 190LPH OR A 255LPH WITH 42LBS INJECTORS, AND YOU THINK THAT THE IGNITION COIL WOULD DO THAT TO THE CAR

so have the cap rotor wires and plugs been replaced recently??

stang6942

yes new plugs and wires also had cap replaced about 3 months ago

have you pulled any of the plugs out lately to see how they look? are they fouled out or do they look ok? what is the plug gap?
