Hi
I have a 2003 c230 Kompressor coupe
Before the car went into storage it started a problem as such;

-My check engine is on
-The engine shakes hard from side to side and runs very loud.
-The smell of fumes coming out of the muffler or exhaust tipareraw and smeelslike alcohol (ethonol) or mechanic said "rotten eggs"
-There is small amount of water coming from the exhaust
-I didnt drive the car much after but in first gear the car picks up very hard, shakes, and is loud and with very little power
-My fuel consumption has noticibly increased as well

I took the car to a well mechanic where they deal only with German cars and they ran a computer scan and told me as such
-temp coolent sensor is detected
-Ignition 2,3,5 are missfired and couple more which i cant remember
-They suggested a good tune up
I will take it this Thursday for through checkup but need your guys help and heads up in what i might be getting myslef into..
THANKS for your time.
