I had these codes come up this weekend, I erased them and they never came up again. I did a search here but all that came up were the last gen. trucks. Do these codes have the same meaning on both gens? My truck is a 05 screw 4x4 5.4.

 

Take a look at your S&B cai and make sure everything is snugged up and fitted good.

Those codes for running lean...

 

Thank you.

 

I changed my air filter this weekend and got those same codes.I started the engine and it kind of shook and the CEL came on.When I removed the MAF sensor side of the filter housing the MAF sensor plug connection grommet came loose.After I re-attatched it and cleared the code all was well.

 

I checked everything last night and all seem well, I reinstalled my Troyer tune and we will see what happens. Thank you for the info. Ive been car shopping lately so the wife has been driving the truck.
