92 300E idle problem

[lerrysan]

Hi,
I just bought a 92 300E last week. I got a good price on it because the ABS light was on and it had no A/C. Turns out that the A/C had a unplugged wire and when I plugged it, it started to work just fine but my engine wouldn't accelerate when the compressor went on. Last Saturday I was taking a cruise on my car when I decided to hit the overdrive and see the responce on my car. As the car accelerated into overdrive it suddently stalled. I had to get it towed back to my house. I thought that it might be the fuel pump or the fuel pump relay. So someone posted something about the the fuel pump relay getting a loose solder point or something so I removerd the relay and there was nothing wrong with it. I did however clean the contact points because they were a little dirty. To make the story a short, the problem was the rotor and the distributor cap. I replaced them and the car started up fast and the ABS light went off. When I turned the A/C on the cars idle rose tocompensate for the lose, "something it wasnt doing before", but it's out of control, when the car is cold the idle works fine but when the car is hot the idle goes out of control and it turn off on red lights or on stop signs. Anyone have any ideas....."I ran out of ideas"....lol
