Question about 1998 Mercedes-Benz C-Class

1 Answer

Iv been having problems starting my car. Especially when the engine is cold. It take a few starts before its able to idle. When Im driving it doesnt have any power and cant get the revs above 3000 and the fuel consumption looks like its increased. Is this a problem with the fuel system or could it be electonical, wiring or anything?

The mass air flow sensor is probably the issue.if the check engine light is on,have it scanned by mercedes or a shop that knows the car well.The newer ones have a electronic gas pedal,and when it goes,the car loses power,but it will set off the check engine light.The idle air control valve can cause idle issues,but will not usually affect top end power.

without seeing where you are taling about im guessing it to be noise from air going past the idle ait solenoid at the throttle body, since it will be open farther when cold. if that doesnt make sense, try explaining hte noise a little better. i really dont think its anything to worry abotu if it only does it when cold.

It sounds like you may need valve seals.
The oil sits in the head after the engine is cut off and leaks around the seals into the cylinder.
When you start the engine it burns the oil and sends the smoke out of the tailpipes.
It does not hurt anything much if it is not to bad.
