If you have the codes just find out what they mean and fix the problem

P1136 - O2 sensor rich, bank 1/sensor 1 (that would be the pre-cat sensor on the drivers side)

P0300 - Random misfires

P0400 - EGR System

Could be a leaking EGR valve, leaking injector(s) on drivers side.... probably a few other things. Or could be a faulty O2 sensor.

A scan log would help diagnose the problem.
