So ive searched the forum and tried a couple of things but every situation is different so ill make my own thread.
I just swapped in a 6 bolt in my 2g and when I did the initial startup my car would idle at 4000 rpm. So I adjusted the biss screw all the way, adjusted the tps, adjusted the throttle cable, fixed any visible boost leaks and my car now idles at 2100 rpm. My safc tps signal shows 28% throttle now coompared to 40% when I first started adjusting.
What else am I missing that can drop down my tps signal and drop down my idle or do you guys think its something else. I cant adjust my throttle cable any more but that was one of things that made the most difference.
Thanks in advance.
 
Same thing just happened to my motor. Turns out my o2 sensor had been reading some trippy numbers. Swapped it and it ran fine. Hope that helps!
