Many thanks to all those who helped me get my no-start to start on 85 740GLE. It was partly due to dirty contacts in distributor.

Now I've got it started and the thing is idling at 2100rpm! And it idles rough at that!

I can't get down any further than about 1500 by screwing the plastic screw (in throttle body) in almost all the way. Then it won't start.

I've tried to disconnect the AMM, it smooths out momentarily and drops a couple a hundred then creeps back up.

I've disconnected the constant idle motor connector-no change at all. I pretty sure it's working. I just cleaned it out, and rewired it.

Throttle body is clean.

All vacumm hoses that I can find are connected and tight.

The coolant sensor gave me proper ohms when I tested it. I've checked wiring to this when I rewired them and if I remember correctly they were okay.

Some other checks-

I've disconnected vacumm hose to fuel regulator, idle goes up a couple hundred. I apply vacumm to it, drops a couple hundred, (still 1800RPM).

When I first start it, it will start after three tries, then when it starts it will rev up to about 2000Rpm then die. It won't stay started until I pump gas.

Sometimes it will be running at 2000, then sound as though some one took their foot off the gas, and drop to about 1200, then roughly stumble back up!

If I step on the gas pedal it will go up to about 4500, but I haven't tried it any higher.

Any body got any suggestion?

Thanks.
