If the engine always runs cold, it will be running rich, uses fuel and
possibly floods on accel.

Most of the codes are set when the engine is at operating temperature. If it
never thinks it has warmed up, codes may not be set.
I'd replace the thermostat and if symptoms persist, have it checked with a
scanner (much more comprehensive than a code reader).

Then there's always the possibility that the SES light is blown out. Do you
get the check engine and service lights at key-on lamp check?
