Hiya,
Sooo fed up with the Merc these days, any advice on the problem below would be great thanks.
The car has been running rough recently, with my Mrs saying that its loosing power. In the past I have replaced the mass airflow sensor twice over a couple of years, seemed ok to me, but I drive the Merc nice & steady, my Mrs floors it (says she does'nt)
Today:
Just pulled & inspected all 4 plugs - All Very sooty.
These are my thoughts:
Can't be a coil pack as all 4 are sooty not just 2.
I think I need to replace the MAS yet again (why would this keep failing?)
Or, am I replacing the wrong part & should maybe try replacing the lambda sensor instead?
Cant tell you how much im fed up lol.
Should I just take it to an expensive garage & plug it in to the fault code reader?
Thanks, Chris & Sandy.
