Question Codes

Hello together
I'm here since a long time but never posted something.......
Had a problem with my 2000 GP GTP today:
Drove down the highway...at about 80 or 90 km/h I put down the pedal. Car runs, supercharger whines bt then came the service engine light flashing. I released the gas and the light goes off and all was normal. Car runs normal no lights all ok.
At home I take a look for some codes (have an aeroforce gauge)
Codes are:
P0300 and P1441
The first is something with misfire, the second something with the EVAP solenoid
The only thing I did was to install a powerlog. Maybe a problem with this?
Is this a big thing if it goes off and will not came back?

Does someone had the same problems? Maybe the cold winter weather? (Got a GTX hood with RAM air)

Thanks for your answers

did you remove your spark plugs when you installed the plog? if not go buy new plugs and change em all. cause you cracked one or more most likely.
 
Something is causing the P0300 code, so it's likely the plug or wires.

Either they got hit when installing the plog or when you removing the wires they got damaged. I'd start there before jumping to the coil packs or ignition control module.
