98 4.6 stumbles on acceleration from stop
i have a 98 f150 with 4.6. has 240K miles on it and still runs great...minus a small hesitation/stumble on accel. I have replaced plugs, wires, 02 sensors, fuel filter in the past year. could it be a tps or iac sensor? I have a code reader that gives me the readings for these sensors. it only hesitates going from a stop. if I hit the gas at anything above idle, it has no miss. runs fine other than that.. thanks again for the help
