Hi all,
My W203 C180K has started to misfire on start-up. It's been happening, occasionally, for a few months, but now becoming more regular. It will misfire and run lumpy, I turn it off and restart and it runs fine. Once going, it seems to run fine as normal. It throws up the engine management light sometimes, but not always. The most recent codes I read using a generic reader are:
P0303 cylinder 3 misfire detected
P0302 cylinder 2 misfire detected
P0172 system too rich (bank 1)
I replaced the plugs, air filter and fuel filter. It didn't fix the problem.
I wonder if it's a coil pack issue, or something more complex. I realise this could be many things, but if anyone has some suggestions it would be helpful and much appreciated.
Thanks
