A check engine light along with a dramatic drop in power (code P0299 low boost and code P0016 cam timing) led me to bring my F150 to the Service Department. After a week to get an appointment and two days diagnosing the problem, I was told they couldn’t find anything wrong. The check engine light? I was told there wasn’t one. (There was when I parked it in their bay). The power reduction? Their tech couldn’t duplicate the problem. (I had been limping on it all week). I was told to bring it in next time the check engine light came on, and oh by the way, that’ll be $150 please. When I asked what I was paying for she asked if I was trying to get out of paying! CThe engine light came on the next day and had a hard time getting to highway speed. Again. Bring it back? No thanks.
