94 explorer running funny
strange problem i cant seem to pinpoint
94 exp, 4.0 sohc, 4x4
idles fine, maybe a tiny bit rough. rpm range good with no load, revs fine. driving though it has no guts, and it will not go over 2500 rpms, bogs out when i stomp on it, max speed of 50mph.
new coil pack (tried 2)
swapped out the maf sensor, it ran better but still boggy.
fuel pressure perfect throughout load and unloaded engine, idle and key on engine off.
new fuel filter
new air filter
no codes either............
any ideas would be much appreciated
its just funny, idles and revs fine not in gear, even stomping on it, its ok, under load it bogs like a mother...
oh yeah, dropped the pipe before the cat and still no change, except the loudness, so the cats arent clogged either
thanks a ton!
