How to Identify Engine Misfire?
1 Answers
Remove the ignition wires one by one. Below are detailed explanations about engine misfire: 1. Definition: Engine misfire refers to insufficient engine power caused by malfunction, where a minority of cylinders among the total number fail to operate. Engine misfire can shorten the lubrication oil usage cycle, easily cause sudden stalling, high fuel consumption, black smoke emission, and power loss. 2. Causes: The main causes of engine misfire originate from the ignition system and fuel injection system. If severe burning occurs on the contacts of the distributor cap in the ignition system, it may cause spark jumping, mostly occurring between corresponding terminals on the cap, resulting in severe idle speed fluctuation and significant power reduction.
