My 1991 Ford LTD sputtering and bogging down when accelerating
This is a 5.0 302... Sometimes it accelerates decently, but not as strong as it used to... other times it sputters and slowly starts to accelerate... then occasionally it damn near stalls out... barely a crawl sputtering and backfiring... I release the gas and press until it finally catches... It also cranks a bit slow... New starter, distributor, cap, rotor button, wires, plugs, water pump, and cold air intake... Any suggestions on where I should start looking for trouble?
