My car has an emission control system purge flow fault, is it expensive to fix it? How much aproximately, and should it be fix immediately?
An evap fault will not cause any damage to your car or cause it to breakdown.The price depends on whats wrong with it.You didn't state any info about your car or the code that it has.You can wait to repair it unless your state has OBD2 emission testing.If your state does you will fail the test.
Reply to Davo/diablo666's Post: The code is OBDII PO441, I also find out by reading more about the purge flow that it has to do with a sealed gas tank filler cap and a purge valve, probably that's what is defective. It said that if that valve goes bad the engine vacuum draws fuel directly into the intake system and it also can fouls the spark plugs. This maybe can explain why my car at a start seems like is not getting enough fuel and it is slugish for 5 seconds. So it is the valve in my case or what needs to be fixed and approx. how much?
By the way it is 96 Chevy Corsica
That code is for no flow during purge.You will not get gas going into the engine from that problem.If no vacuum hoses are off or cracked you probably need an evap purge solenoid or an evap vacuum switch for the evap system.You could do this yourself if you have tools.Both parts are available aftermarket for under $40 total.I can't be more specific price wise because I don't know if you have a 4 or 6 cylinder engine.
