07 fx 4 bucking on highway?

[slickrick]

I was driving home from work this morning and my truck began to buck or jolt on the highway driving around 100km/he. It would happen every couple of minutes. No engine light came on so I’m stumped. Anyone have this happen to them or know what it could be? Any help would be appreciated

There can be codes even if the cel was not illuminated, so looking for those is a good idea.

I have had that symptom with bad gas (gas with water in it) and with a sick fuel pump in the past. I expect that a plugged fuel filter could do the same thing.
