Idleling problem
 

Alright guys I have a 94 FD3S base model and [I]m having problem with the idle. I rebuilt the engine and StreetPort with non-sequantial turbos. Im still runing stock ecu and stock injectors. I already break in the engine and its boosting 10-12psi but when i go to a stop light the car is idleling at 1500 to 2000rpm and sometimes it idle 750-900rpm. My question is my ecu is it gotta be change or is the cold and warm weather or something else? I would appreciate if someone could give some tips on how to fix the idleling.:dunno: p.s. emmission, cat, any restriction has been eliminated
