Run 2 squirts alternating. I've found out that when running fuel AND ignition with the MS, that the stock ECU freaks out a bit and will start to surge a bit with the Idle Air control valve..With so many things disconnected from the stock ECU, it for some reason has a hard time keeping a steady IAC signal. My only solution was to remove the IAC and block off the IAC port in the throttle body. I then used the throttle stop screw to adjust my warm idle speed. It works well, but when the engine is cold, you have to use the gas pedal a little bit to start it, and keep it running for 20-30 seconds till some heat builds up in the engine. If it's running lean at idle, try richening it up in the idle bins, and DO NOT run closed loop idle off of the 02 sensor. The engine runs much smoother when its in the 13 AFR range rather than 14.7:1..

I have found a abnormality in the air density correction factor in the code, at leat i believe so, that when the IAT rises up in temps, it pulls out too much fuel..There is a table for correcting this, but that may be a bit too much to delve into at this point. You have to run closed loop idle control, and adjust that table till the o2 sensor correction is always within 5% adjustment, all while adjusting that table. Maybe look into that when you get everything else taken care of and understood.
