Check for vacuum leaks. build a leak tester and track them down.
Re: rb20det problem

Try cleaning the iacv. Maybe its got some crap or dead insect in it
Re: rb20det problem

Re: rb20det problem
so, checked out the switch, and the tps for good measure
no dice, nows its running ritch as hell, like 10 afr at idle.
drives decent, still a 10 afr.
and does the retarded timing at cold start.
Could a bent CAS wheel be causing all of this? Imean its tweaked pretty good..
Granted I don't have an after market FPS to go with 255 walburo, wonder if that blew the stock pressure regualtor?

Re: rb20det problem
on cold start up it runs fine once its warmed up then it start runing up and down, runs fine other than this boost great , just on idle it revs up to about 1000 for a few seconds then drops nearly dies then back up to 1000
