An intriguing one. I have a W124 multivalve (OM606) diesel estate on my drive which finally I want to get back on the road. A couple of years ago I took off the manifold to get to the glowplugs to replace them, of which I managed 5 of 6. I never got round to putting the manifold back on, but last weekend a mechanic friend did so for me. Now when it fires up, it idles at about 1400 rpm and then goes full tilt to about 4000 rpm without me touching the throttle.
What might be causing this?
