Ok here goes....

2013 EL Limited, 5.4L - NO CODES AT ALL and doesn't seem to have any weird noises

New cams, roller followers, lifters, Melling 340 HV oil pump, New timing job, New Coil Packs, plugs, injectors, cam/crank position sensors.

Cleaned MAF and throttle body (Looks like brand new on the inside)

Little bit of an intermittent rough idle in D , P, and R..

Any thoughts ideas? I kind of don't want to bring it back to the shop who did the timing as they had to crack it open 3 times before they got it right.

I have forscan but I am not sure where I need to look
