Engine Performance problem
2001 Ford Ranger 4 cyl Two Wheel Drive Manual 117000 miles
I have a 2001 Ford Ranger 2.3L. My truck idles fine, but when it's going down the road it sputters and backfires some. It only does it if I really press the gas pedal down, it does fine if I ease into it. I have already changed the fuel filter. Could this be some water in the gas? Or do I need to have some servicing done to it? Sometimes the " check guages" light flashes (NOT the CHECK ENGINE LIGHT)when it sputters, but all guages read normal. I'm puzzled on this, anybody have some suggestions?
