- 1999 explorer sport
I have a 1999 Ford explorer 4.0 OHV with about 120000 mile on it. The problem is that when I shift the vehicle on gear the engine sound like It is missing. I take the vehicle on the road and it shaked at slower speed. I have changed MAF, Intake gasket, Spark plug and wires, Coil pack, IAC with nothing getting better. My engine idle about 1200 rpm( engine runs fine with missing sitting in park or neutral) and when I shift it into gear it idle @920(Misfiring). Was giving a code of P0171 and P0174 when I changed the IAC valve but went away when I changed the Intake gasket. I changed the intake gasket a couple of day ago and the code have not reappeared. The problem is on going
