Hi,
I've noticed a slight hesitation when I accelerate from a full stop.
I was told that the air filter may need changing.  I live in Calgary
and this is an extreamly dusty city.  So it's likely true that the
filter is clogged.

The car is a 2002 C230 Kompressor Coupe.

Where is the air filter located and how is it checked / changed?

While I'm here does anyone have a url to a service like web site for
this car?

Thanks.
B.
