shaft position sensor it went about 5 miles light came back on he then installed new plugs and wires it went approx 20 miles engine light came on and still missing at that speed he then did another reading and smoke test and did upper intake gasket set , EGR controil solenoid still mising around 30-35mph he said use overdrive off in town and that should not let it miss at that speeds I still have a miss but it does great at all other speeds he said fords are good for this and riuning transmissions if left to drive in overdrive at all times. WHATS NEXT I have diven about 30 miles engine light is out but still missing at 30-35mph
Missing at around 30-35 mph. with engine light on my mechanic installed new cam- on 2002 Ford Windstar
Since he is already putting in parts that it hasn't needed,have him throw in a new ignition coil...or find another mechanic.
