I have a built b18a in my 99 hatch. Im using gude cams n ecu, aem cam gears, ported n polished head, je pistons n rings, b16 tranny , ...etc...I've had this setup for about a year n half but now it starts to hesitate if i go too low on gas. And it will also hesitate for the rest of the next tank...I've already changed my plugs, fuel filter, n wires, but i duno what is going on with my car. I also have a surge problem./ (idels for 1100 to 1400 constantly) Ppl have told me its because of my f.i.t. valve or aic, but i dont know wich one it is, or if its that in the first place. any suggestion would be helpful. thanks...mike
