2002 GT 4.6 Anyone know what codes these are? PO602,PO605,PO1211,PO1690. Diablo scanner reads these codes are normal for a tuned car. Check engine lights has come on twice it shows no other codes. Thanks for your help.

try reseting the tune back to stock and contact the tuner. most likely this is a bad PCM but there could also be a problem in the tune...
you could not find those codes because they don't exist.. He needs to rescan and post the codes. Maybe they were a B code but those are not powertrain codes.
