Searched around, plenty of threads on wandering or surging idle, but haven't seen any on a consistently high idle... looking for any suggestions.
When I first started the engine, I was really happy that it fired up and ran very well. Idle was above 1,100 but I didn't have any slack in the (new E34) throttle cable. So I took away material on the throttle adjuster such that I could get the specified amount of slack. This reduced idle but not significantly.
Also the car always idles lower on cold start and then the idle comes up as the motor warms up. Is this a problem with the ICV? Not getting any check engine light. Planning on getting it tested for any vacuum leaks but I can't imagine the car would hold a steady idle with any significant leak.
Other than that, it's honestly running awesome. Only issues are an exhaust rattle which I hope is just a loose O2 bung screw, and the aux fan switch isn't functioning with the a/c button (yea it's kinda ghetto but I ran out of time and it worked easily at first) as of a recent move (car was shipped cross-country... 3 days after I got the swap running). Hopefully some simple wiring.
Oh and for those interested: I had to make a quick video of the first start-up when I picked up the car from the muffler shop. I'm running some eBay shorty-style headers (came new with the motor) and a UUC System-U (new) from an e36 M3, with custom pipes connecting them, basically straight pipes with the single UUC muffler.
Will make a better video when I get rid of this rattle. In love with the sound, and it's actually quiet when I want it to be.
