Signs Your Ignition Timing Is Off Some things to look out for: Engine knocking: Engine knocking occurs when the air-fuel mixture is ignited too soon in the cylinder. The mixture then pushes against pistons that are still trying to compress the mixture. This causes loud pinging sounds to come from the engine.
