Hi....I have a 1995 Camry with a 2.2 4 cylinder & 136,000 miles. All of a sudden the engine started to stumble from the start. Also it stumbles at a steady RPM. However it seems ok at high RPM but can feel a noticable engine rumble traveling down the high way. I pulled the plugs and checked the spark (all checked good). However, one plug showed soot as opposed to the rest. I checked sensors associated with the fuel system but they checked good. Can this be a fouled injector?
I still need to check the Emissions side of the house. Any help would be appreciated. THanks
