Im getting my car dyno tuned and i wanted to fix this problem before i get it tuned. I have been having an issue with my rpms staying at 1500 rpms and runnig badly with my foot off the gas and still in gear cruzing down the road. My a/f meter starts to jump around. But sometimes it seems to be fine and my idle stays at 850 like it should. And when it is able to idle fin it dosent run like crap when my foot is off the gas and cruzing down the road.

Sorry, I've been working on the car....

Don't touch the screw on the TB.
Incorrect base idle can cause the revs to 'hunt'
Other things to do are clean the TB and AAC valve..and if you're feeling brave clean the MAF with some electrical contact cleaner/carb cleaner/brake cleaner but use the spray from a distance on the wire coils so it just washes the dust off.
