Long time lurker here, finally got around to making an account so hopefully I can turn myself around and take better care of my beloved 1999 c280.
Over the past 3-4 months, I have been experiencing an interesting intermittent issue. Every once in a while, my car will hesitate when accelerating and then pull forward (surging I think). During this, the CEL will flash for a second or two, and then just become solid.
After going to a local trustworthy shop, they ran the codes, multiple engine misfires. They recommended that I initially replace the plugs, and if that didn't work, to move on to the wires and possibly coils. I got the plugs replaced, and the car drove silky smooth for like a week, when it happened one more time (only once). I went back to the shop, still getting the multiple engine misfire codes and then misfire codes on particular cylinders.
In addition to this, every once in a while my car will idle really roughly. Its bizarre, sometimes it runs perfect, sometimes it doesn't. After doing some reading, I'm thinking about replacing the MAF with a bosch unit from one of the two primary sites mentioned on these forums. Does this sound like a MAF issue to any of you other w202 owners?
Also, I am very amateur at repairing cars myself, and am looking to learn more, so any additional advice on things I should order when possibly ordering the MAF that will be useful in the future for maintenance, please let me know.
Thanks for the help everyone, I hope I havent broken any cardinal forum sins within this post
