Answer 1

Hi there,

P0301 is a misfire code on cylinder 1. This could be something simple like a bad spark plug or wire. Possibly an ignition coil.

The code P0401 indicates a problem with the egr valve. This could be a sticking egr or a problem with the sensor that tells the computer the egr is working properly.
