Fast idle on hot start up

Hello all,
My '83 930 has a fast idle issue, but only when started when warm. Say I stop to get gas...fill it up..then start it. It will have an idle around 1600-1800rpm, and slowly, very slowly comes back down to 1000rpm, but that takes about 2 1/2- 3 minutes. Any clues out there?
The car also has the occasional annoying hard start issue after the car has sat for over 1/2 an hour. I've changed the accumulator & front pump check valve to no avail. However it can still be the check valve in the fuel head, or a leaky injector.
I do not know if the 2 issues could possibly be connected or not?

Any help is always good help, so thanks to anybody willing to throw me a bone.
