A lurker here with a short story to save for the future generations..

I too had a 930 come in with high idle, 3000 or so after warmup.
Long story short, it turns out the elay for the under tank fuel pump had a bad contact. Cheap aftermarket "URO" brand red relay. In fact it fell out of it's socket when the fuse box cover was pulled off.

Car ran "ok" and when idle was adjusted down, it would hunt and surge, especially with the AC turned on. With the new relay, the idle speed went down and smoothed out, and after adjusting it to around 1000rpm, everything seems fine. The A7C doesn't drop the rpms as much as it did before either.

Engine has unknown history, someone has made a lot of modifications and the electrical and vacuum systems are a nightmare.... heh.

Anyways. Thought I'd share. Back to lurk mode.
