Angry 190E Fuel Injection Problems

I own a 1989 190E 2.6, Here are the symptoms: The engine will start, power is very smooth, in high rpm ranges, once I start letting go of the gas at about 1500 rpm's the engines starts to feel slugish, if I let go of the gas the engine will stall, I can not mantain an idle speed at all, the engine can be running all day long from 1000 rpm up, but once I let go of the gas the engine will stall, sometimes after this happens I can't start the engine again after this happens, sometimes I have to wait about half an hour before I can started again. No matter what I do I can start the engine after a good rest, and I can keep it running as long as I dont go bellow 1000 rpm's. The EHA valve was replaced, I have adjusted the clearance of the fuel distributor plunger according to the manual, and it had little effect on the problem. Questions: could I have a bad Fuel Distributor? Bad Injectors?

When a car(engine) doesn't idle properly yet runs good on the road, either the fuel mixture is off or the vacuum in the intake is too low from leaks or low compression.

What would be the compression range for a 190E 1989 2.6 engine?
