Your very welcome trust me here they dont like these plugs, I want to get this fixed without you spending way to much money replacing parts not needed. You can come back after plugs are changed and I will walk you through everything after. If its needed. The gap is really important as well make sure all plugs have spark coming from the coils. Than have them check the codes again I would suspect another code other than the P300s which are just misfiring if its another issue. Thanks
