Something is wrong with your ECU or the diagnostic function if your car isn't setting codes with those symptoms. Or, the codes are being set, but because the power to the ECU (through the red wire and 25A fuse) is intermittent, the codes are being wiped every time you look.

Look that wire over carefully. Check for 111 and smelly exhaust (they should not exist together) and if so, get a meter on the oxygen sensor as Trev suggests.
