Engine Mechanical problem
1993 Other Saturn Models 4 cyl Front Wheel Drive Manual 170000 miles
SC1 with a SOHC. Just changed the oxygen sensor. Plugs, wires, fuel filter, and pvc valve appx 6 months ago. When you feather the gas quickly 2 or 3 times the rpm's drop very low, the car sputters and shakes then returns to idle speed. If you rev the car up, lots of black carbon spews out of the tail pipe and leaves black marks on the ground. Car seems to lag power under 2500 RPM. If you put it to the floor, car lags until 2500 RPM, once you hit that thresh hold it takes off and you feel a surge of power.
have the same problem?
