    the car is a 96 dx, and the engine is obd2 spec b16a with obd0 injectors (can this be the problem?) i have rc injectors, waiting for the clips.

    i have 2 issues that i just can't get rid of, even after i took it to a dyno:

    1. running lean around 1500 rpm, hicups due to no o2 signal in closed loop.
    2. bad transition from anything more than 10% throttle to under 10% throttle.

    now, i've tried to add fuel around 1500 rpm with narrow throttle and it doesn't help at all. is there anyway to fix the problem without tearing out the whole harness (o2 sensor was replaced?)? for the bad transistion problem, is there anyway to fix it with the narrow throttle and wide throttle transition %?
