Hello. Not sure where to post this but I have a 2009 G550 that is giving me misfire on all driver side cylinders. I've swapped coils and plugs both new and with other side. I have even ran a straight pipe thinking it's a clogged cat. I have heard somewhere that it could be an ECU issue. Anyone else able to chime in or direct me would be appreciated.

You're in the right place 👍
