I have a 1984 380se that is havin a problem of cutting whenever i stop the car at traffic lights stop signs etc. what are the most likely problems to cause this? I am currently diagnosing the car myself. i have discovered that when the car is "idling" the flap that moves up and down when revving does not close airtyt (which i assume it should") when it is at rest position. Secondly, there is a slight oil leak on the left side of the engine, looks like some of it drips into the spark plugs. engine cranks, fuel pump is working. i avoid the car from cutting by frequently putting my gear in "N" and then revving up before putting it into drive. if however it cuts, it is so difficult to start back into idle again. Someone please help me as i have become imobile due to be a problem that sounds to be minor.
