Hello, I am new to the forum. I have a 92 500e and for the past couple of years it has hesitated upon initial acceleration or under light load. The car has been maintained immaculately and this problem has the dealer and independent mechanics stumped. Fuel pump, injectors have been changed. Plugs changed regularly and changing the very "inexpensive" spark plug wires had no effect.
Does anyone have any ideas? The problem is slight but bothersome to me.
