Anyone else have the cats break loose inside ? On the drive home last night, took off from a light felt as though the truck was on the limiter (lower rpm than normal)smoking real bad out of exhaust , ignition breaking up and the S/C @ max boost. Truck is completly stock . Let off gas cleared up but rattle from cat area . A few miles later same thing , but now engine has miss and sounds like it collasped a lifter. No cel. no codes . 39k miles . I know some had engine problems early this has been fine since day one. Now at FORD dealer hoping for mercy since its out of warranty.
