Alrighty so I’ve replaced spark plugs twice, wires twice, coil, cap, rotor and distrubor, and have even gone as far as hollowing out the cat, It’s a misfire code I can drive it for a hour and then all of sudden it runs like complete shit, it stalls(it’s an automatic aswell) some times i don’t know what else to do to it, any ideas on what it could be?
