1320 ignition signal circuit
1402 EGR system fault detected
105 absolute pressure sensor
300 multiple cylinder misfire

Based on the problem, start by checking the EGR. From there I would go to the manifold absolute pressure sensor. Any of the three items can cause the problem. You have to check each.
