PO300 and P1399 are random cylinder misfire detected.

Code 300 is a random miss not serious enough to peg a cylinder, code 302 is for cylinder 2 and code 304 is cylinder 4. Code 402 is for an EGR flow problem.
Its possible the EGR problem is causing the missfires. The computer sets the 300 codes when RPM drops on a cylinder. The computer does not know why. So it could be spark, fuel, compression, or a vac leak.

P0304 indicates misfire in the cylinders..
A misfire can be triggered by several situations. inadequate fuel, ignition misfire, insufficient air flow, too much fuel, incomplete compression... If you look at freeze frame data with a scanner you can see what the conditions were when the code was set, this will really help to pinpoint the problem.
