Hey guys.I know some have had this issue. I have a 2019 S550 with the 10speed.Early March, I started having misfires after a fuel up at a local station. My vehicle was in the shop 6 days, I got it back Tuesday Morning and the dealership said it was fixed.An hour later, same exact issues were seen. Today I dropped it back off and I'm not sure what the next steps will be. I suggested to them to check IMRC.
So far this these are the "repairs"
-8 new plugs
-cylinder 2,3,4 all got new injectors
-replaced a high pressure injector on cylinder 3.
When I picked the car up, it was In a bad state. They said it was probably bad gas. Everything was fine so I drove for an hour that's when the issues came back. Very noticeable on WOT. The car just backfires so bad on throttle off. Hard to start after start after it sat for a few.
Anyone else see this lately.The car is in Stock file mode so I'm not sure what's going on with it.
