02 C230 K Cylinder Misfiring
So when I drive my car I have the following problem:
I drive for a while, and then my check engine light will come on and the car will sputter and shake(on acceleration) and just a strange vibration.
If I pull over, turn the car off, and on, the problem goes away till the next time.
The codes are Cylinder 1 / 2 misfiring.
Any ideas what this could be?

Dealer replaced coil pack #4 first - worked fine for a while, then same problem.
It went back again, and they replaced #3 and #4. No problems since.

Sounds great, I have a cylinder misfiring in #1 and #2, so I am going to replace those (just ordfered from the dealer)
Thanks again for the quick responses.

Throw some new plugs in while yer at it too.
NGK Iridiums are about 6 bucks most places.
If you have a pulley, there's a thread on that other forum about
getting a cooler plug.
And, yes, I had the same problem, and they replaced coil #4.
It got progressively worse till finally it died on a trip and I made it back
on 3 cylinders.
How did you know which cylinders were misfiring?
