Idle screw all the way in....performance low?
The idle screw is all the way in on my SR20-DE (Almera GTI) It has just had the co levels checked and all is ok, timing has been set and all ok...........surely the idle control screw should be out a bit and not all the way in......would it not restrict air being all the way in or is it ok? Car's performance is ok. I have only had it 2 weeks. It has 110,212 miles, full Nissan service history a 4-2-1 manifold, 3" Powerflow exhaust and modified but its not as fast as most of my other 2.0 16v cars I have had such as a Golf GTI 16v, Astra GTE 16v and my friends Peugeot 306 GTI 2.0 16v is a lot faster than my Almera?

The idle screw being in will not affect performance, other than your idle performance.
The idle screw should not be all the way in. Your idle can still operate decently well with it all the way in, but that's because the other valves are being forced to work over-time.
Go through the factory recommended steps to set the idle and get that screw up some.
