No more idle
#3
Uncap the idle air control valve, plumb it back into your intake line.
If your idle is still unstable, check for a vacuum leak in the intake manifold...specifically look for the plug at the rear of the intake manifold. Consider dumping a can of "Throttle body and air intake cleaner" into your idle air screw and IAC valve.
Thank you for being smart and not trying to boost on stock fuel management.

My guess is that there is a leak in your intake piping or where you capped the IAC. Normally a leak would help raise idle, but since it is being sourced from the engine bay rather than being recorded by the MAF, there is extra air entering the engine that the ECU does not know about. If there is a big enough leak (i.e. a loose pipe coupler) the engine might start at first because it runs rich on cranking, but then it will stall because the mixture will be extra lean due to the excess air that the ECU does not compensate for.
Removing idle control shouldn't be a problem, as long as you don't use AC, brights, etc.
