Flashed the code for service engine light (07-05) EVAP Contro Sys. After looking up the codes it could be alot of things, just wondering what the most common problem and fix was. Thanks Derwin

 

check this : look at p0440.

Thanks....but I was hoping to narrow the list down. I know what it could be. Any others have the same?

 

Probably a bad vent valve and charcoal canister.
They have been redesigned a few times. so you will need to get them both.

 

Would this cause my fuel milage to go down. Just replaced my KS 2 months ago...plugs(iridium)summer,fuel filter (summer) cleaned plenum(3 months)....now I don't notice that air pressure when i spin my fuel filler cap?

 

Would a bad filler cap cause this...I don't know what would have happened to it.

 

Any ideas??
