Guest ekvh Posted March 12, 2009 Share Posted March 12, 2009 I decided not to hijack a post. How do you know if the canister is working properly. I remember hearing a while ago that a bad canister can kill your gas mileage. Anyone know if that's true and how to check it? Link to comment Share on other sites More sharing options...
padgett Posted March 12, 2009 Share Posted March 12, 2009 From: http://www.familycar.com/CLASSROOM/emission.htm"The function of the fuel evaporative control system is to trap and store evaporative emissions from the gas tank and carburetor. A charcoal canister is used to trap the fuel vapors. The fuel vapors adhere to the charcoal, until the engine is started, and engine vacuum can be used to draw the vapors into the engine, so that they can be burned along with the fuel/air mixture. This system requires the use of a sealed gas tank filler cap...One common problem with this system is that the purge valve goes bad and engine vacuum draws fuel directly into the intake system. This enriches the fuel mixture and will foul the spark plugs. Most charcoal canisters have a filter that should be replaced periodically. This system should be checked when fuel mileage drops."
