The contact owns a 2006 Ford F-150. The engine light illuminated and the vehicle began to vibrate while in traffic. The vehicle was towed to dealer, american Ford. The dealer replaced the # 6 fuel injector. At 9,670 miles, the same failure recurred, and the dealer replaced the # 5 fuel injector. At 9,735 miles, the engine light illuminated again. The dealer stated that the catalytic converter failed because of the fuel. The current mileage is 10,765, and failure mileage was 7,462.
Two separate occasions I experienced a fuel injector failure on my '06 F-150 while traveling on I-65 on 10-10-06 and on I-10 on 10-14-06. I was told by a dealer in culman alabama that I could drive it on to memphis with the engine light on. Upon arrival in memphis dobbs Ford told me there was nothing wrong and I had to take his word. On my trip back to tampa the engine light came on again and I had to towed to american Ford in tallahassee. The replaced #6 fuel injector. Later, while in memphis #5 injector failed and was replaced at landers Ford in collierville. A few days later the engine light came on again and this time it was the catalytic converter, which had to be replaced.
After one week of ownership, on 9/2/06 the truck dieseled when started for about 5 minutes before idling. It could not be turned off. When it finally idled, the check engine light was lit, it idled rough, knocked when accelerating or under a load and the gas mileage dropped as I was driving about 2 miles per gallon. From this point on, it was hard to start. This happened with 1000 miles on the truck. It was taken for service and the dealer told us that the catalytic converter and oxygen sensor was defective? this seems to be the result of this problem and not the problem as upstream fuel/air mixture problems cause leaning/riching which will manifest itself as cat or oxy sensor defects. These parts were replaced and 1 week later the check engine light has re appeared.
