Miss fire on cyclinder #4
I was told by my stealership that my Enginee #4 cyclinder has a miss fire. So how did this occur? What am I looking at in terms of repair? How can I make this problem go away?
Is this something I should be concern of?
Please advise.

Basically, something in your ignition system isn't working or similar. Dirty/old spark plugs or plug wires, or failing coil packs, can cause this. Furthermore, dirty or defective injectors can do it, too.
How many miles are on the car?
You want to do the cheaper things first. If your car is below 100k miles, don't worry too much about your coil packs. Swap your plugs for cylinder four out, along with the wires. Run some techron through that sucker.
I'm going through this same exact issue.
Also, your stealership may lie to you at times. Does your car shake at idle in drive? Have you ever felt a sudden drop in power out of nowhere, or a stutter? Perhaps a symptom in my thread I linked?

#4 is at the rear of the engine. Most likely a bad coil pack. Or a bad spark plug. If you have more than 75k miles, I'd change the plugs, and change the coil pack on #4 as well. Coil packs are some $60.

NO WAY. REALLY?! I thought cylinder four is at the front of the engine, driver's side, as far from the driver as possible...

So a new set of spark plugs, Plug wires should be good?
Nope, I have got any expereinces of what you mention. Still pretty solid. Although on the first start up, it does makes some enginee noise. Perhaps this is normal for Mercedes?
Is there a distrubuter in this car? If so does this have to be replace? How about cap and rotor? Please excuse me, I am a noob here
. I used to drive an integra and these are the items I look at when ever I play with miss fires and such.

I have about 89500 miles on it. When you said techron, you mean that addative fuel injection bottle you pour in while pumping gas at the station right?

^Great write-up for the v6.
OOPS! My apologies, 2004 C230's still have the kompressor/4banger. Just use that v6 thread for reference then.

For now, I would say cylinder four's plugs and wires. I'm sure you know the flow of things when talking of replacing plugs, but just a reminder! Remember that dielectric grease and anti-seize!!

Yea, I guess the V6 don't kick in until 2006 models. But even so, they have transmission problems. So the question is minor enginee problems or tranny problems that affects the enginee. After reading so much horror stories, I am wondering if there is any solid MB models at all.
Oh.. One more thing, supercharge vs just V6, I guess it depends who you ask about which is fun.

Get techron form autozone or something. Much cheaper there.

It's the black bottle. Also if you have oil leaking in your cam magnets this can cause a whole host of false alarms and is a general nightmare.
The C230K does not have engine problems, and the C230 V6 does not have transmission problems. The early cars were problematic electrically but the engines and transmissions were always solid.

As for c230k, well, I am sure this forum pretty much speaks for it. With the hose, senloid and such. I think that is pretty much "minor" enginee problems.
Or I am just being a little extreme on this.
Oh, also some miss fires on some cyclinder as well.

really? I used google and did this search. 2006 c230 issues and you have a nice time reading all the problems. Among the frequent titles, it shows that transmission problems.

Those are recalls that all manufacturers have. Search Google for info on 1999-2003 Accord V6, Odyssey, Acura TL/CL and that will expose what a REAL transmission problem epidemic really is. The 722.6 5AT and 722.9 7G transmissions in the W203 are solid. We very rarely hear any any transmission woes on this forum.
