Misfiring low RPMs and low gear, rough idle
I've had an evasive check engine, can't seem to catch the code before it clears. Symptoms:
2019 C63s Coupe, 31k miles
- Twice a month it misfires and throws check engine in comfort mode in high gears or low RPM. Idle becomes really rough, spiking 500-1krpm up and down on idle. Restarting car clears it, and car becomes normal again
- Never have any issues in high rpms or in sport mode.
- 1 in 10 cold starts have a rough idle with RPMs spiking sporadically up 100-400rpm quickly before dropping
- Fuel consumption possibly up
- Engine temps seem higher than normal, and engine heats up quicker than normal
