Can a misfire cause loss of power?
A misfiring cylinder can cause a proportional loss of power. For example, if one cylinder misfires in a four cylinder engine, the car will lose 25 percent of its power. Damaged, worn, or bad spark plugs, or a weak ignition coil can cause a loss of spark, and therefore, a misfiring cylinder.
What damage can misfires cause?
