At first it just shut off at stop signs and stop lights would not idle. Vital fluctuated up and down. Then one day it would crank but not start. So I pulled the fuel pump fuse and it started but smoked real bad whitish grey smoke. Anyways, I checked my oil and smelled strongly of gas, my spark plugs were all black the cylinders and when I pulled the plugs look down in the holes and you could see the gas in the cylinder gas was even coming out the valve cover gasket. What's wrong with my car?

Good morning,

This sounds like you have injectors that are dumping too much fuel into the engine.

This could be from either bad fuel injectors or a faulty ECM commanding them to continue to deliver fuel when not needed.

The injectors need to be tested to be sure the pindles are not seating.
