Just replaced the dash on my 88 325is yesterday and I went to my friend's house afterwards and when I come to a stop at a light the idle stays at around 1500. After about a minute, it slowly drops to like 1200, and then 900-ish. I didn't do anything to the engine and everything works just like it did before the swap, obviously except the idle.
I did disconnect the battery, but everything is stock, so I don't see why the friggin thing is suddenly acting up.
I've already driven around 60 miles and it still does it so...ideas?
