My wife was at the store and came out and started the Flex to come home and she called me and said it made some kind of clicking sound and then seemed okay so she drove home. I came home a little bit later and I came out and started it and it makes a continuous rattling sound and then stumbles when you try to rev it up like maybe it's a timing chain issue? However, it's not throwing any codes.

Has anyone ever come close to putting 19 gallons of fuel in? I have never gotten more than 16 gallons in mine. And thats milking it down to virtually empty by the gauge. It seems like I should have a few gallons left based on mpg.
