    I need a little help. I have a Second gen B16 installed into a first gen CRX. I am running this with a PR3 ecu and first gen B16 dist. I have 2 new O2 sensors and my fuel pressure is at 31 psi at idle. I have the second gen high impedence injectors so I have pulled off the resistor box. I am reading that my air/fuel ratio at idle is near correct (maybe a little rich), but as soon as I hit the gas pedal, it goes full rich.
    Can anyone give me an idea as to why this is happening? I am going through a lot of fuel. :angry:
    Any possible solutions would help. I am going to pull the fuel rail and injectors to check the spray patterns this weekend, but I am running out of ideas.
