I have FIC injectors and I am having idle issues as well. I am idling at 15.8-16 afr, and it seems like it gets a little miss every once and a while at idle. I have really big cams, but I am going to try to figure out what it is. Im am going to try to get it to Evodynamics this week I will report back.

 

me too same injector same issue...

 

I never did figure out what the issue was. I tried a set of FIC 950s as well and still had the same issue. Just recently I put in a new fuel filter and O2 sensor but I haven't had a chance to try it again.

 

Bringing it back from the dead, did you ever have a chance to try it? Interested as my car has similar symptoms at idle with stock injectors and I'm looking at going some larger injectors in the near future
