Having a very intermittent problem with my speed 6 shuddering and misfiring like crazy while accelerating at low rpms between 2-3k. It’s super random so very hard to get a log of it but the one log I was able to get I noticed that the fuel rail pressure dropped below 100 psi for about 20 seconds before it started misfiring. Figure it’s something to do with the HPFP, where should I start? It’ll drive fine for days at a time, some days it might be just a blip, some days it just goes crazy, super weird how intermittent the issue is to me
