I Got a 90 civic hatch, i just finished swapping the D16 out for a B18B1. Everything runs great, lots of power. The only issue's im having is first the idle, it idles rough and when i try to adjust it it doesn't seem to really change at all. Second problem is when im driving, and i push on the gas just a little bit it stutters, push a little more and the car starts taking off.....??? Any help would be great Thanks
