what will it cost?

How much will it cost to repair the problem that codes po300 po303. Caused?

Answer 1

Hi there,

Basically with this code it's saying there is a misfire on cylinder #3.

This could be a simple repair with an ignition coil which then the car would be worth repairing. If you have other problems with the car using coolant then it could be a head gasket causing the misfire which would be quite a bit more.
