the skipping and bucking are getting worse as the weather here gets colder.
Changed oil to rotella 5 40 and added hot shot secret about 250 mi. ago. No change, ficm voltage is 48.3. I've read through other members issues and they seem to be a little different than mine. Whats' my next step, injectors? Any help would be greatly appreciated.
 
Looking like injector. Do you have anything to pull codes with?
