My daughter told be the SES came on so I scanned the codes and found an evaporator leak fault P0442. When I check for the gas cap it was gone so I assumed the mystery was solved. Once I replace the gas cap and fired it up, the engine ran really rough - when I scanned again I got bank 2 lean codes and misfires. Note that the evaporator error has cleared itself since the screen shot. Seems a little too coincidental that these faults are not related to the missing gas cap, but it still does not name sense to me. Any ideas?
