Car Evap System

Rough idling, gas smells in the car interior, poor performance, and reduced fuel economy are just a few signs that the car EVAP system is failing. Common causes are leaks in Vacuum Switch Valves and damage to hoses. Related are the various issues plaguing various Fuel Storage Parts. Cars with over 60K on the odometer should be checked for clogged Fuel Filters, and whether fuel pumps and lines are in good nick. Using lower octane fuel can also be part of the problem.
