Is P0455 A code for purge solenoid? that could create an internal vacuum leak when activated usually after running for a few minutes.

Load related issue - could be fuel pressure or bad cap/rotor/wires ...Mileage on engine? Maintenance? ALSO COOLANT TEMP SENSOR FOR PCM may be stuck cold ./not the sender for your guage/light
