Have OBD Codes and now the car shakes!!
I have a 2003 Maxima SE 6 speed that I picked up recently. The codes that I got are P0300 P1448 and P0455. I did check the fuel cap and it looks to be new so it couldnt be that. The car has 128,000 miles and the owner said the spark plugs have never been changed. I checked all the hoses and did not see any leaks or anything. Today I was driving the car and anything under 2000rpm's the car would start shaking no matter what gear it was in. Should I start with the spark plugs? Then after that?

Change your plugs asap! avoid driving or you'll eff up your cats, injectors, etc.
Unfortunately, you'll need to replace your valve covers with 04 ones (gaskets too) test your coils-goodbye po300.
The others are evap/gas cap codes. Tons of us have these codes and just live with them-unless your super picky or live in cali. I've had those 2 codes for over 30000k and get great mileage and breeze through emissions. after your done, seafoaming is probably a good call.
