i had autolites which i was a little skeptical about, so i switched over to some ngk's that i had and i still have the same problems. it's the most noticable when i'm accelerating at about 1/4 throttle, and sometimes it seems like it's not getting enough fuel, and i can hear the engine sputter because the exhaust sputters. if i give it more gas it's ok. i put new plugs in over the summer, and i have a new rotor, cap, and fuel filter. what are they sypmtoms of improper gap? that's the only thing left i can think of. thanks.
