Misfire and I need help

Hi guys, 

 

Hope all is well, 2005 de - right so I changed one of my valve covers a while ago, putting everything back together didn't go as well as hoped, I took it to the garage and after a couple of gasket changes there was still a misfire, the checked my injectors and replaced some seals, they noticed and showed me pictures of hairline cracks in 4 of the injectors, so I ordered some second hand and had them fitted. 

 

Now - code p0304 sometimes and p0300 most of the time and flashing eml light. I have switched coils packs and spark plugs and the p0304 remains (in the same way) . Today whilst taking it for a run to see if the problem persists when warm I noticed in the torque Pro app that my 02 sensor on Bank 2,sensor 2 is irratic and not in line with its brother on Bank 1. Could this be an 02 sensor? Or is the sensor reacting to the misfire? And any other tips or points? 

Thanks

 

Toby
