My new/old toy has a problem that has confused my local mechanic. I still had to pay his bill of course.
Whilst the engine sounds healthy enough, it is ticking over at 1500rpm in neutral and 1000rpm in gear.
All Internet info put this down to the air control valve which I replaced with a used unit bought on line.
It is not surging just running too fast and also appears to be running rich. The idle control screw is in as far as it will go.
Could anyone recommend a garage in Manchester area that are familiar with theses old Mercs.
Oh I forgot, it is a 1980 450SL..
