Idle probelm.....

[Simon Quested]

Hi All

My car wont Idle well under 1100 rpm.
Car specs
Ford SOHC 4cyl "pinto" engine
Ported head
Mild "turbo" cam said the wrecker I got the motor from....could be anything. 
16th of an inch taken off the top of the pistons ( was a turbo engine, turbo died, 
saving dollars for the replacement )
Aftermarket old analog efi controller on it. ( Had 2" SU carb when the turbo was 
on)
Nissan Silvia injectors (1800 cc turbo) I don't know the rating
Toyota injection manifold.

It has new spark plugs NGK AP5FS and new plug leads.
I pulled the injector rail out and turned the key on, no leaky injector. 
I have an O2 sensor and the car runs well as long as you are over 1100rpm and 
It's reading above ~.7 

any suggestions????
