Both of these appeared on my car last night.  There's an earlier thread that mentions this could be evap, mass air flow or fuel pumps.  The car as 77k miles should I just replace all of these things.  My only testing tool is the durametric - which in this case is not very helpful pinning down the actual cause.

These codes are the fuel pumps telling you they are going to die and leave you stranded somewhere.  First time I have ever had to have a car towed because of a mechanical failure.
