I need some advice. I'm buying an 05 FX4 supercrew from my brother in law . The truck is bone stock and the engine and trans were replaced with 70k on them now ( 180k on the truck ). It run ok but seems a little sluggish. My brother in law is not much on maint. so it could be just a dirty air filter. It has no gauges
so I don't know what is going on with the engine. Do I need to worry about the oil or egr coolers at this point ? Thanks for any help.
