hey guys, how smooth does your truck run? like when you are accelerating? i have a 2006 fx4 5.4 and it seems like its got a bit of a "roughness" upon accelerating.

Smooth as glass

yeah i feel like im going crazy. I swear my engine was smooth as glass a few months ago and now it just doesnt feel the same as it did, inless my head is really messing with me. I replaced all splark plugs, new throttle body, fuel injection flush all with dealer parts. Just doesnt seem as smooth as it once did

mabey its a dirty fuel filter or something like that. I have a habit of running it down to empty alot, probably sucked up some dirty or rust from the tank.

Clean the MAF sensor....that will cause an issue if it's dirty
