idle?

[turbospd]

What could be some of the reason for me having a low idle some of the time? like 500-600 RPM's sometimes. Most of the time 800

i heard if you spray nitrous into the throttle body under full boost that it will solve that problem

WTF ... Maybe he was referring (somehow) to cleaning the throttle body. If that is what he was trying to say, it's a good idea. Run some cleaner through there or take it off and thoroughly clean it. You may want to check your ISC to make sure it is functioning properly. Also, see that your BISS is adjusted properly. If you have a vacuum gauge you may want to throw that on there as well, to check for vacuum leaks or problems in the valves/timing.
