Please help - I have just bought an '83 280 e (w123) with 115k on the clock. It drove fine on the test and then when I got home last night after a trouble free 40 mile journey, I turned into my street and the car just died - picked up - died, etc.

Eventually by pumping the gas pedal I managed to struggle home. I have checked dozens of posts in this forum but can't find the exact problem.

The fuel pump was replaced 2000 miles ago, oil pressure seems fine, I checked 3 of the plugs and they are all fine.

I do know the idle is too high and the engine runs fine in P or N and at a decent speed but as soon as I select D the revs drop and it starts to stall when I press the accelerator.

I didn't think a car this old had any fancy ECUs - any ideas what it might be.

Many thanks!!
