I have a 2004 C230. It was idling rough so I took it to autozone to have them run codes on it.ALL the plugsandwires codes came up (I think a total of 10). I'm guessing I just need a tune-up? Am I correcting assuming this or should I take a different route?

 

May I ask how many miles on your car?

 

The 271 engine had many, many problems Have someone look at your engine further. May want to have a compression check done.We have seen everything from leaking cam adjustersa to valve problems.

 

I have a 98 C230 mine did the same thing. It also shook the motor, check the ignition coils and the order they are in also may need to replace the wires as well. That sound bout right LMK what it was. [:'(]
