I don't know the answer but i have the same problem. I have cleaned all the egr system, changed the throttle body gasket, changed plugs, wires, cap and rotor button. I still havent got it fixed. There is a vacuum motor on the very back of the motor, behind the bpt valve, and I'm curious as to if it could be the problem. If anyone has the answer, PLEASE, type it. This has really got me confused to what it could be.
its a Nissan for starters but it could be the plug wires or the plugs or the distributor
Time to replace seals, this usually causes misfire.

p0302 is cylinder 2 misfire, you need to fix the cause of the misfire. Possible causes are plugs, coils, injectors......
The Ignition Coil is the one that cause misfire or Spark Plugs
no, they fire in the order of the plugs on the intake
