How can an ignition module cause an engine to misfire?

An ignition module controls the timing and delivery of electrical signals to the ignition coil, which ignites the air-fuel mixture in the engine's cylinders. If the ignition module malfunctions or fails, it can lead to incorrect timing or inconsistent spark production, causing incomplete combustion. This results in engine misfires, reduced performance, increased emissions, and possible damage to other engine components. Regular diagnostics can help identify issues with the ignition module before they lead to significant problems.
