Who knows 5.7 fault code diagnostics?

Well I'd hate to pull apart the front of the motor only to find out the timing chain was fine then have to do the intake for the vvt or the other way around the problem is I'm just not sure which way to go? BTW I drove the truck all over yesterday and about 6 key starts the code hasn't come back yet.

Did you drive it under heavy load/acceleration? Pcm will need To meet the fault tolerance to set the code. Pulling the intake is not hard with only a few basic tools. Hardest part is getting the connector unplugged at the very back. The vvt solenoid is at the frt of the engine and held in with 1 ten mm bolt, twist the valve a few times to break the o ring seal and it will come out.If you still have the original style solenoid it will have screens, that are usually all torn up.The one with the wrapped spring is the superseded part and I haven’t seen one of those fail.RJ
