1989 Toyota Van 4 cyl Four Wheel Drive Automatic 157, 00 miles
My van starts up when cold on all 4 cylinders and sounds normal then starts running on 2 after a second. The dead cylinder's spark plugs have fuel and some sludge on the tip of the threads. Not the spark area.
It started doing this all of the sudden and was running very strong. I replaced plugs, wires, dist. Cap, rotor, coil, O2 sensor and catalytic converter.
