I have searched on these forums and read all about the warm-up regulator and the dreaded high idle when warm issue. My car (87 US spec 930) doesn't idle quite as high as somewhen fully warmed up, usually from 1800-2000 rpm. Tapping the gas to see if it is sticking or even pulling up on it with my foot doesn't fix the issue. The other data point is that I get the popping and cracking on decelleration that a lof of folks describe as well. It may be more notiable on the car because it has a spot exhaust on the car. The exhaust and a 1 bar spring are the only mods.

I wanted to see if there are other things I should check, before I drop a bit over $1000 on a new WUR?
