Hello, I bought a 2008 Mercedes Benz CLS550 from auction and I am having the notorious #1 cylinder misfire. I've replaced call coil packs and spark plugs. Symptom still remains. Injectors and compression are good and tested wiring from ECM. I am at a lost as the car idles rough but drives well on the highway. I'm only concerned because of the check engine light that is really the annoying part that tells me there is still something wrong. Any help and or ideas what to check next before I make a decide on rather to cut my losses or make a unscheduled dealer appearance that I don't want to make... HELPPPPP :)
This is the best instruction video I have ever seen. Seriously! It is systematic, logical and easy to follow. Thank you very much for your help.
Nice explanation 👌

check your o2 sensors
Is your cylinder then
Were you able to figure out what was wrong?
I have a 2007 Mercedes c230 1,3,6 no spark
I wish I could have him look at my car
