hello people i have a problem on my 1993 320 cabriolet mercedes auto its idling up and down so bad, i removed the fuse number 7 for the auto transmission electrics and the car idles perfect but when i put the fuse back in it starts to idle bad , the fuse controls other things like waterpump fan heater and couple of other things , im baffled at what it can be, i dont want to drive the car without the fuse as it controls other things but what can i do its driving me potty, shall i leave the fuse out any help?
