bought truck new in sept 2006 traded in a 2004 tundra(which i really liked,except for the bed,very shallow,but have great power and very good gas mileage).i had owned a 97 f-150 4.2 v-6 but sold it a year later because of the 4.2 were blowing up around 85,000 miles.when i bought the 2006 the ford dealer told me they had fixed the problem and gave me extended warrenty on the power train for nothing.dose anyone have an 06 with high mileage on it or have had any troblems with the engine????
