I recently got done building the h23a1 in my prelude and now i have been having a problem with the car stalling out when it comes to a stop, i have checked for vacume leaks but nothing, sometimes the car doesnt stall but it bogs down bad when you come to a stop then jumps back up in idle and runs fine, if the car sits at a light for around 30 seconds to a min the check engine light comes on, it reads out a code 43 fuel supply system,

The motors mods are, cams, cam gears, underdrive pullys, header and full exhust, ported and polished head and intake manifold and air intake.

I have replaced the plugs, plug wires, distributor cap, and rotor still didnt solve the problem
