hello guys,i turn to you as a trust and good friend and i rely on you and your knowledge.MY car is 2003 mercedes c200 kompressor,163hp. the symptoms are : car shaking when on parking, shaking when on drive mode,hard shaking like the car will shut down,when driving it seems like the engine is working on 3 cylinders.I have bod adapter and i did some diagnostic.I will upload the photo for you to see the codes but i don't know what to do. SPARK plugs changed 2 months ago,today i put the old ORIGINAL ONE NGK with mercedes logo on it,but no change.OIL is changed,filters....i have one clue and it is the MAF sensor,but I'm not so sure.PLEASE look at the picture and give me your opinions.

I would try swapping coil pack from 4 with one of the other ones and see if problem moves or not.

Thanks for posting this thread. Had the same thing happen to my car last night (P0304), and shaking got progressively worse, so I'm in the same boat.

Guess it's coilpack 4 as well. After doing a search last night, I didn't see that anyone had any problem with that particular code (I'm guessing your other code is either of the O2 sensors) that was anything other than plugs or coilpack (cp was far and away the leader).

Good luck with your fix - I'm just leaving my car as is for about a month - will be driving my CRX that I had put into storage for the winter already for the next couple of weeks, then a cruise for two more, then deal with the Benz then. I'd rather not think about it for a while.

Today i went to 2 people to see the car.the one couldnt do anything,thinga became more aophisticated.the car started to work very loud like a diesel motor and knocking a lot. I scared and the car was druven to service. The second said something about a chain and some tooth wheela ( i dont know how its called) and said if this is the peoblem will cost about 2000usd....i hope will be the maf sensor or sometbjng else,just not this!what do u think? The first guy said the car have perfect compression,but afyer a 1 week with new oil the spark plugs were black. And he also said that w203 is very often problem
With chains and wheels of the valvea which are 2.
