When our Explorer had 29,000 miles on it, I brought it into the dealership because the check engine light had come on and the vehicle was stalling out at stoplights. They replaced the oxygen sensor, a gasket on the intake manifold, and a fuel injector. Now, 3,000 miles later, I returned to the dealership complaining about the same problem, except that the check engine light had not come on. At times, the Explorer sounds and feels like it's going to stall out at stoplights or when shifting from reverse to drive. The dealership had the truck for 2 days and ran up 11 miles on it, but they could not recreate the scenario. They could find no problem at this time.

While driving noticed smoke coming from the exhaust system without prior warning the vehicle started to lose power. Took the vehicle for service, and the consumer had problems with the engine head gasket, the dealer replaced the engine, and there was a problem with the oxygen sensor. Vehicle has been in the shop for repair service eight times, and the dealer still can't determine the problem. Vehicle is back in the shop for repair service.
