Replaced the MAF - the car is going appreciably better but still
stutters on occasion - I'll check the lines tommorrow. So many thanks
for the recommendation.
As an aside - I thought I had all the necessary tools - but no - Merc's
done it to me yet again, this time needing a star screwdriver bit with
a hole up the middle. My Mk1 hacksaw came in useful again!
Are there any recommended manuals out there for the W210 series -
Haynes in the UK haven't done one as yet.
