spark plugs

Oh, and as far as the e3 plugs go, never used them in a vehicle, but I did try them in a lawn tractor that I was having some trouble with the motor not running quite right despite a carb clean and all that sort of stuff. Put the e3 plugs in and the tractor ran noticeably better. Well worth the money for use in a lawn/garden tractor. But those are a bit simpler of an engine than a truck.

I added the charging system also. If you have a volt meter do the load/noload test to see if it is up to snuff. Takes about ten minutes or less, under charging system diag in the tech library. Other than gear box PM all that other stuff should be done before troublshooting anything code related. In my opinion
