an idling question

I have a 1989 325is with an idling issue. Idling used to be all over the place, surging from 750-1200, sometimes idling up around 2000. I found that the throttle switch was bad, and swapped that out. For a couple days it idled perfectly. Now it starts and idles fine, but when I give it some gas to start driving then let off the gas to stop, the idle remains up in the 1500-2000 range. If I sit for a while, the idle eventually creeps back down to around the normal 800rpm level. Sometimes it comes down quickly, sometimes it takes a while, but it eventually comes down.

Of note, the car will start fine cold, but will take a long time on the starter if I've just shut it off then tried to start again quickly. Leaking injector that could be related?

Any ideas?

Has this been covered a thousand times already? If so just please point me in the right direction. Cheers.

Here's the car:

solution

Seems to be sticking throttle cable. Shot some WD40 down there plus a bit of oil and the problem hasn't arisen since.
