[QUOTE="Fendert65, post: 427958, member: 18671"] Thanks Gary747. A lot of the tune up/ regular maintenance is always done. In fact I do pull the plugs occasionally just to check burn/clean and check gap. There are no lights/codes and my first instinct was that Cat but and trying to not just throw parts at the problem so I thought I’d get some outside opinions. The engine temp is a concern, it has never run hot but right now it is running kinda cooler than normal. I’ll go through your suggestions and see where that leads. [/QUOTE]
