Engine Chugging & Sputtering
I have a 94 Pathfinder 3.0 V6. Recently, it began having problems with excelleration. At startup, the truck is okay. After driving for a while, truck begins to sputter and acts as if it will shut off. Sometimes, when I let off the gas pedal and then press it again, it goes okay. But, sometimes this doesn't even help. I have had the truck serviced. You know, tune-up, oil change, plugs, distributor, wires, etc. The check engine light has yet to come on. Have no idea what to check for. Maybe Catalytic Converter? Injectors? How would one go about cleaning the injectors. Any help would be appreciated.
