If you have a retarded ignition, your spark plugs will ignite the fuel mixture in the combustion cycle too late. When the timing is “too advanced,” the spark plug fires significantly earlier than intended, starting the burn cycle prematurely. The further it is advanced, the earlier the spark will fire "before" TDC. Too far retarded=White/Grey Smoke Too far advanced (far advanced)=Black Smoke Not a very finite adjustment though, just a basic "way too much" or "way too little" advance on the injection timing. I checked with my timing light and I'm only getting 30 degrees max. Hesitation and backfiring will accompany the loss of power causing the plugs to foul leaving them with a black “sooty” appearance.

If you hear pinging or knock, feel power loss, or notice poor fuel economy, consider a diagnostic with a capable scan tool to check spark advance, knock sensor data, and related systems. This causes a loss of power and poor fuel economy. Advanced timing is needed for combustion to happen but then when it is too advanced, then an engine knock may occur. An advance that is retarded will result in a long and fast crank (hard start). I set my advance curve up for 20 deg initial and 38 deg max. Timing advancing too far, too fast.
