Dear All
My 940 car now have some abnormal run. As I turn the innition key to the position before starting, the light signal on dash on only three, lambda , parking and oil pressure. Does anyone know what going on.?
Next I start the engine, it run not smooth seemed that too much fuel injected. Because I see black smoke out of the exhaust and with choking when rapid accelereate.
So I go to a garage shop to fix these matter. They clean the followings...intake accel flap, air mass meter, ignition distributor unit and change the fuel regulator. All still not solve the problems. The dash check light still unlight on some.
And black smoke with little choking and vibration.
I also notice that there are some oil leak at the side under the intake the manifold, may be from the flame trap. I would like to know how check and clean the flame trap.? Can anyone teach me how to do.
And last question, I suspect some sensor to be bad may be temp sensor or knock sensor...does this can be malfunction..? So I will buy new parts and to replace them.

Thank you,
