Hi everyone I need help I have a 07 f150 super crew 4x4 5.7 Triton I have changed the ecm,maf,throttle body vct sealanoid cam position sensor crank position sensor all four o2 sensors I start it in runs ok for a minute then starts running rough and goes into fail safe mode what else could be wrong I don't have but 113000 miles on it

 

It sounds like you threw a parts department at your truck...

You will need to scan the codes and post them, before we can help.

 

The only thing you didn't change is the spark plugs. Why did you throw all those other parts at it? Did you have a solid reason for changing all that stuff?

You need to get it scanned with a high end diagnostic computer by someone who knows what they are doing.
