Engine Management Light

[Locoshaz]

Hi guys,

I've just bought a 2001 CLK 200k. It's in great condition both inside and out. However, the engine management light came on a few days ago. i took it back to the guy i bought it from and then we took it to a few garages who put their equipment on it. The diagnosis showed a misfire on 2 cylinders. The general consensus was that it may be a problem with the coil packs. Now the car drives fine, i've even taken it to London and back, (250 mile round trip). The only thing is, when i'm at lights or in traffic, the car shakes ever so slightly, sometimes you can hardly notice it. We've changed all the plugs and 2 of the coil packs. The light hasn't come back on yet but that's because i haven't pushed it. I can't keep driving it like that though as it's a Kompressor and i want to give it some gas on the odd occasion.

Has anyone had any similar experiences? Does anyone know if it could be a more serious problem? I'm thinking of pushing it, then if the light comes back on i'll have to take it to a main dealer and get a full diagnostic done.

Any advice/help would be very much appreciated.

Kind regards,

LS.

it could be the ecu, the coils are well known for blowing both pms and hfm type, but have it diagnosed 1st

Coil pack are a common problem, you have got to take it out for a hard drive, it was made for that, you will never know if you dont.

My dog shakes when she sees a rabbit and I won't let her run after it - perhaps your car feels the same!

i just had similar problem have a look through my threads..... but my misfire was a big one.... turned out to be crap in the fuel... swap the coil packs around with the ones that work, then try the plugs leads etc,,,,, also get ur mass sensor checked...

lots of info. on threads for <mas>< maf>< kompressor> & also a idle regulator(failing) for when air con is on Got to say you'll learn to live the light being on or you'll soon be on first names with your local stealer & well out of pocket!
