Can a Bad Battery Cause a Misfire? Complete Diagnostic Guide
Yes, a bad battery can cause an engine misfire. While misfires are traditionally caused by worn spark plugs, failing fuel injectors, or low mechanical compression, a weak or defective battery starves the ignition coils of the voltage needed to generate a strong spark, while disrupting sensor signals sent to the Engine Control Unit (ECU). How […]
