Maybe you can help me with a problem I now have. I have a 84 500 SEL which was missing at idle but run great at anything above idle. When I checked the plugs after it had been idling for a short time, I found one plug was black and wet with gas. When I checked it with fuel pressure, it had a very slight leak below the 40 to 50 lbs pressure cut off. New injector fixed it. Now my problem. How do I convense my car that the injector couldn't cause this problem, so replacing the injector couldn't possibly fixed it. I guess the car just wanted to take something impossible and generate a make believe problem and play with my mind. Oh well.
84 500 SEL (307,xxx miles)
