Hi

My Engine check light appeared a few days ago and also car started to run a bit rough as if it was misfiring. I also noticed recently that the engine would run very fast when first started until it was placed in gear and would be clsoe to stalling at lights etc.
After looking on the forums I guessed the MAF was faulty and replaced the original with an aftermarket model.
Anyhow the car is still running awful and after checking the codes I have Engine misfire on cylinder 4 5 or 6 and also air intake codes which I guess still points to the MAF.

Any help would be appreciated, I will post actual codes later as my laptop has died on me!

Code P0300 P0306 P0100 P0105

The car is a E240 W210.
