I just finished my recent project on my 87 951 which included new vacuum, fuel, coolant, power steering lines. I had the intake off for all of this, and now I can't get the car to idle hot or cold. Just wants to stall at idle. It is very smooth and sounds good at RPM above 1000. Not sure if it is as simple as the idle adjustment on the throttle body or something less obvious.

Fairly new to this car so any help would be appreciated.

Double Check your Vac lines, make sure everything is hooked up and no leaks. If you have a vac gauge it would be a decent indicator, since you want above 11HG... more around the 15 mark for a cold start. If you vac lines seems good and connect right, then look at the ICV and make sure lines are connected. If you still have nothing then test the TPS and ICV, see if one needs to be replaced.

My car did the same thing last summer and I replaced the ICV and TPS and it fixed it, but since you just did vac lines and such I would start there first, triple check everything.

Is the ISV valve stuck? You can pull the big hose off (the one that comes down from the intake manifold) and squirt some carb cleaner or similar in there.

Is the TPS adjusted properly? It should make a click when you crack open the throttle.
