Most likely the timing is a little too high for low grade octane. Either go to a higher octane ( $$$$ ) or best, with a timing lite, just lower the timing till it stops knocking for the fuel that you are using.

Spark knock in a 1992 Mercury Topaz 2.3 engine can be caused by a variety of factors such as using low-quality fuel with a low octane rating, incorrect ignition timing, carbon buildup in the combustion chamber, or a faulty knock sensor. Proper maintenance and using the correct fuel octane rating can help prevent spark knock in the engine.

How does mercury outboard 60 hp e60elcia work?

The Mercury Outboard 60hp E60ELCIA uses a combination of fuel, air, and spark to power its engine. Fuel is injected into the combustion chamber, mixed with air, and ignited by a spark plug to create controlled explosions that drive the pistons. These pistons then turn the crankshaft, which ultimately propels the boat forward in the water.

Ignition module on a 1984 Mercury Topaz?

The ignition module on a 1984 Mercury Topaz is responsible for controlling the ignition coil and firing the spark plugs. It receives input from the engine's sensors and determines the optimal timing for spark ignition. If the ignition module fails, it can cause issues such as engine misfires, stalling, and difficulty starting the vehicle. It is typically located near the distributor or ignition coil.

What are the knock senors for on a 2004 Chevy truck 4x4?

Severe spark knock (pinging) can damage the engine. Knock sensors detect spark knock (pinging) in the engine. They send that info to the ECM (Engine Control Module). The ECM makes temporary adjustments in engine timing to eliminate the spark knock.
