Dear Fellow members
Season's Grtgs frm Singapore!!.
Well, I noticed that recently, my 240SE 1991 has been running rich, from observation that the exhaust pipe now has a lot more carbon.
Changed the air filter but to no avail.
It's also running "hotter" especially during stop lights, short traffic jams etc.
Flused the radiator, but it didn't help too.
The lambda light doesn't come on at all.
Could it be the cat converter?, oxygen sensor? Air Mass Meter?.
Also, after a short run and I need to re-start the car, engine will refuse to idle, it cuts off. I usually have to put my foot on the pedal, until the revs goes up to about 1000rpm. Lift off too soon and the engine cuts off.
Any advice would be appreciated.
Rgds
