Z22SE - P0300 Random/Multiple misfire detected

Good afternoon guys,

I was driving the Mrs's car and decided to overtake a slower moving car, I used a bit of acceleration to get past - probably a bit more than the Mrs would ever use... pretty much straight after overtaking I got noticed the car was shaking a bit then the engine light started to flash... Got back home and plugged it into my OP-COM reader and it came up with the p0300 code.

I have since changed all 4 plugs and changed the coilpack (the coilpack I sourced from a local scrappy and came off another 2.2 Z22SE however the coilpacks dont have the same part numbers..... would this matter?

I have played about with the injectors today unplugging them one by one to see if there is much difference which there isnt..

Any data I can read from OP-COM to help diagnose?

I have not touched EGR Valve yet as I couldnt see how this could be causing such issues?

What else would you try?

Thanks for reading guys

coil pack or injector would be the likely issue, try swapping the injector number 3 with number 1
