sbn1979 Posted July 11, 2017 Report Share Posted July 11, 2017 So I have a evo 8 with a pnp on it, with an AMS intake and unknown similar style throttle body, using the air screw to set base idle, but now and then fluctuates to the point of cutting out, any tips on sorting this?icv steps currently set to 500 Quote Link to comment Share on other sites More sharing options...
