Engine Performance problem
1986 Mercedes Benz 300e 6 cyl Two Wheel Drive Automatic 133, 00 miles

I'm having difficulty starting the car. It'll turnover but not catch. Sometimes it can take 5 minutes of constant attempts before it actually starts and then the idle is rough and sometimes shuts off. Under acceleration, it initially has little power and there is " popping.&Quot; Once it gets underway, the engine is smooth but recently it shuts down at idle.

I'd also like to know where I can get a diagram of the fuel system.

Thank you very much.

Best, George Lutz
