1 owner. dies going down road.also sporadic tac., new tune,changed cam sen. twice and crank sensor 3 times.tack was ok after first cam sen change. before recent crank sen change it died and it took about 30 min for mechanic to get there then it just started. he wiggled the crank sen and truck died but restarted.it did get a crank sen code.i'm thinking of buying the next cr/sen at dealer if it is any different. any ideas????????????
This truck stops running for no reason, then will start if it sits for a few minutes. It will cut out at times and the tach and everything shuts down, then it's okay for a few minutes or months. Sometimes will not start when cold. this is an automatic, V8, 4WD
Sometimes hard to start; sometimes engine dies while stopped at a redlight or stop sign. Sometimes it dies while cruising. Usually I shift it to neutral and it restarts in this condition. Occasionally while running engine will suddenly buck like it has a drag cam in it.
Had plugs, plug wires and distributor replaced but still have problem. Coil is fine,
Truck stalls at various times, high speeds, in normal traffic, at stop signs,starts some times but mostly after sitting 10 to 15minutes
stop running going down road.re start some times. replaced cam sensor first and ran for 2 to 4oo mi then stopped running again. replaced crank sensor 2 times in 300 miles. now has 62k no problems so far. is a wonderfull xcab sport,v6 auto. aqua color original no issue paint.some mechanics say get sensors from dealer. I didn't.
