I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)

No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... at about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.

I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...

MY research tells me the cam issues are causing these problems pretty regularly. Anyone provide some insight?

 

Probably need to go after the timing, change oil pump while you are at it and vct solenoids ( oem).

 

For it to lose that much power, probably has jumped time. Before any timing work is done, check oil pressure at hot idle. Supposed to be 25 PSI. If below that, changing out timing components is just a waste of time and money.
