driving under normal conditions it runs fine, but when i mash the pedal the 440 starts to pop, it misses,lacks power, it acts like it hits a wall. i checked the timing, all the componets, plugs, wires, everyting, cant get this figured out. maybe a valve train problem? floating valves? sticking? can think of anything else.
whats really fustrating is it starts fine, idles fine, it even revs up in park no problem.
