I know this should probably be in the 1.8 forum, but I figure it's a pretty general question. My motor has always idled high, between 1000-1500 in park. I have never changed the idle setpoint, and the yellow paint on the idle screw doesn't appear to have ever been disturbed. When I got the car, someone had already advanced the timing (I forget what, but it's the common 2nd gen GT setting that was suggested on the tuner forums) and I left it there... would this affect the idle speed? I was already thinking about setting the timing back to factory, and certainly don't want to end up adjusting the idle twice. Thanks.
