I have spent about 4 hours looking at previous posts for a similar problem. I can't find an answer so I thought maybe I should just ask. I have a 2000 Civic SI with a B18C (ITR) motor, tranny, and ECU swap. The car has had MANY small issues over the years and here is another one. The car idles at about 250-500RPM usually but will sometimes idle normally (750-1000 RPM). The car is as great as it ever was as long as the gas pedal is depressed. Doesn't matter if I am going 25 MPH in a construction zone or if I am on a country road with the pedal to the floor listening to the beautiful sound of the N/A motor roaring the Apexi NOIR cat back exhaust. Pull up to a stop light, idle returns to retarded mode and the car dies. Does this sound like a fuel pump issue? I say no because if it was, wouldn't the car act up all of the time? I have new MSD 8.5 wires, new plugs, clean air filter, fuel filter is less than 1 year old, fuel injectors ohm tested good, and I cant find any cracked or broken vaccum hoses. Any help will be greatly appreciated.
