Hi All,

I bought a 1998 C200 manual about 2 months ago. Soon after I realised it was lacking in power and would intermittently 'back down' when travelling at speed, as if I'd taken my foot off the accelerator.

It was also very very sluggish at low revs, so much so that turning across traffic was a risky afair because you couldn't get speed on pull off.

I did some reading and eventually replaced the MAF sensor. Since then there has been more power but still not what I would expect. At times it is still sluggish at low revs. So it is overall a bit better but not right. It also has a very distinct exhaust smell when cold that smells like it's running rich.

Fuel consumption has also not been great. I've been getting around 8km/ltr (or 18.93mpg if my calculations are correct).

So, what else needs to be replace after running a bad MAF for a while?
What else should I check? How do I get this car to perform at full potential?

Other info:
It has +- 180,000kms (112,500miles)
It has a full service history at the Merc Dealership (big selling point for me but been dissapointed so far...)

Thanks,
Jase
