Car shaking with black smoke

08-24-2008, 12:42 AM
I have a 2002 Kia Rio Cinco and have had no problems. Yesterday while waiting to get gas the car started shaking badly and black smoke was coming from the tailpipe. Oil showed low so I added a quart. After getting gas I had to take the car home it was so bad. This morning oil was all over the engine.

What could be wrong? At first I thought it might be an O2 sensor but the front one looked good. I am not sure if there is another one.

I know black smoke indicates rich fuel so I thought of the Fuel Pressure Regulator but, the oil has me concerned.

Any help appreciated.
