Re: Check engine light code PO411
Truck is not under warrenty has 50,000 miles on it. This is something I've never fooled with. I know were pump is but is this in a hose or something. I tryed to buy a Haynes book yesterday but all they had only went up to a 2006. How can I check it when I find it. I did notice the other day the check engine light went back off but the next day came back on. Wife said gas mileage has went down. Thanks for the help. fiserman
