ok so i pulled the plugs, not only were they ****, they were not gapped, so i put in new ones with the proper gapp, and now the truck is idling perfect, but when i drive it hard it feels like abooged down 2 cycle dirt bike, my mechanic said i would need to drive it for 20 - 30 minutes to burn off all the build up, the cel light popped on , which he said would go off once the **** burned off .. ???
Hope this resolves this..
