Hi everybody, new poster here. I have a problem that I know somebody has heard of before. I have taken the car to the shop several times and they just keep changing parts. Here we go....it starts ok when totally cold just by turning the key however after sitting and cooling off for 30 minutes when I turn the key without touching the gas pedal it starts then dies within 1-2 seconds. If I turn the key again it will usually continue running fairly well. The only way to warm start the car is by pumping the trottle while turning the key. This is driving me nuts (have you ever tried to explain to a friend or valet that you gotta do it just so to start the car). I have changed the plugs, rotor, rotor cap, plug wires, all injectors, fuel filter, O2 sensor and air filter. There appears to be no vacume leaks. Car has 147000 and runs just fine besides this problem. Come on guys what are we missing???
Thanks, Alexander

There is a fine adjustment that can be made that will help. The shop has to know Mercedes well. You have to adjust the static height of the air plate. The height is too high allowing for a lean condition when first started. The reason it does not do it cold is because the cold start injector makes up for the unmetered air brought in.

I have the EXACT same problem on my 87 300E. The problem has occurred since I purchased the car 5 years ago with 67000 miles. It now has 167000 miles, no change in the problem. I've replaced all tune up items several times, even tried replacing the fuel pump relay, but it didn't help. Has anyone successfully solved this? I'd be curious to find out more solutions.
