Can a weak ignition system cause an engine to misfire?
For an engine to start and run properly, the energy must arc the plug and keep that arc going until all of the combustible mixture is consumed. Anything less and the engine will be weak, run rough, stall, and misfire. Weak ignition is often confused with a fuel problem since the two systems are codependent.
What are the symptoms of a bad ignition module?
