Sputters when accelerating, or going up hill.
I have a 2002 4.2 with 127k miles. The initial problem was a severe sputter when a load was on the engine. Found a broken spark plug in cyl 1. Changed plugs and air filter 2 months ago. Problem went away, for awhile. It has kinda come back but with less verocity. Changes fuel filter 2 weeks ago and wires today. But when cold it sputters on a firm acceleration or uphill. Once warm it happens a lot less but still happens. No CEL. Any Ideas?
