Misfire

I have found where it is thanks. I'm going to change the fuel filter first, then the crank angle sensor and then who know's. MAF ???

Have you had any water spilled/or entered the cab around the front seats?(BECM).
Water in the in the ECM under the battery compartment would be my first look see.

No water at all. I haven't done the crank sensor yet as I,m still not convinced, but if it persists I,ll have to keep eliminating things, but thanks for your suggestion.
