Cars that are started in the cold and driven immediately or cars that are kept in extremely cold temperatures are more likely to have a distributor cap become faulty. Distributor caps are made out of a plastic material, and plastic that is heated and cooled too quickly can sustain damage. The cap can crack and burst if it is started in the cold weather on a regular basis. If the distributor cap is cracked, it should be replaced before it begins to cause other engine problems.
One of the most obvious symptoms of a bad distributor cap is a shaking car. If the car is at a stop sign or a red light and is idling and it begins to shake, the distributor cap may not be causing the proper rotations within the engine.Learn more about Car Parts & Maintenance
