Dear Friends,

I have this 1998 C230 kOMPRESSOR and the car was running fine, no problem at all, then i had a business trip and the car became parked fro 7 months,

After this 7 months the first time i attempt to run the car it start right up but it was very rough then a sent the car to a mechanic of mine ( not MB specialist at all) and he told me that one of the coils was bad, so we change one coil ( 2 cylinders) and the car was smoth again but with no power at all

If i pushed past After 4000 rpm the engine started to became erratic and loses rpm, so i throttle back and the engine return to work properly

Some time, the engine got scramble thou out the rpm range, but if turned the car off and turned on again it resume to work

Then I thought that the gasoline was old and etc, so I run the car for 1 month in this condition trying to clean the tank and the fuel system

But that did not happens, so finally the situation got worse and now the car does not pass 1600 rpm and the car barely have the power to run in a level street

So I changed the fuel pump, fuel filter, cleaned the fuel injectors ( that was not dirt at all )

But the car still not working It idles smoothly, but if i throttle up it barely pass the 2000 rpm, became very rough and I can it even back firing

I unplugged the MAP ( air flow sensor) but with out it the engine donīt even start

Any help and input will be appreciate

Thanks

Ricardo
