Hello all, Can any one point me in the right direction please as I have a bad misfire in my 2004 Mercedes E200 1.8 (M271) Kompresser engine that I cannot fix? Basically I have checked as much as I know about and still have not found an issue. I am trying to keep the cost down so I don’t want to through new parts at it or bring it to a main dealer. I have checked timing, all good. I have checked compression in all cylinders and they are in between 165 -175 Psi. I have cleaned the MAF. Changed the cam solenoids as I was getting error codes. I have checked all coils, moved them around and pulled the plugs when car is running to hear a rev drop. Checked all spark plugs, plug holes had oil in them from a leak in the rocker cover gasket, changed it also. Checked for a torn tube under the air box and at the back of the air box, have not pulled out Kompressor yet to examine that pipe but the one above it was new and I can’t see evidence of a tear in the one under the Kompressor. What have I missed??? Is there another component that is the cause of this. Just to say the misfire was only noticeable when idling and driving it was fine. Now I feel it has become much worse as the last time I took it for a drive the car was hesitant and louder. If I leave it a few days not started it starts up a lot better, what I mean by this is the engine is not as loud but it comes back into it within 3 minutes and now sound like I have left a spanner in the engine. I have a icarsoft scanner, is there anything I can do with this to determine through live data what the issue is. I have used this to pull codes and have seen many but the latest ones are P201A-000, p200B-000 & p2042-000. Apologies for this long winded question but I would really appreciate some help and detail may help come up with an answer.
