I got these 2 codes and from what i have read intake gaskets and charge motion control valve should fix this if its not an vacuum leak on a line. The truck does skip between 40 and 55 mph the worse on slow acceleration. Is there anything else that may cause these codes and problem. 2005 f150 5.4

How many miles on your truck ? I have an 06 with the same problem and just ordered new coil packs. I have 108k mikes with plugs changed 2 years ago the coil packs start to go bad but if you've never changed the plus I would change plugs and coil packs. How's your gas mileage ?

122000 miles I just bought truck still on first tank of gas. I was thinking about replacing plugs and coils before i installed a new intake manifold.
