    Default 00 SI B20v stumbles

    I have a 00 SI obd2 b20 with gsr head and aftermarket intake.L
    Car ran perfect when i removed the b16 it was just tired.
    all sensors are hooked up and working except for o2 sensors. (ckf sensor, knock, evap on fuel rail all working)L
    used the snap on scan tool and tps sensor is adjusted correctly, map reads correct, no misfires)
    this engine has 50 miles on it since i assembled it. timmlng is dead on. plugs and wires are new.L

    problem: car doesnt idle on its on unless there is tension on the throttle cable. when driving, anything over quarter throttle and the car actually slows down. begins to hesitate, miss, pop, and backfire.L

    help please!!!!
    I have done so much,
    with so little,
    for so long,
    that i can make anything,
    out of nothing!!!

    It may not run it at the max power level but is should atleast idle and accelerate at low throttle. im not out flooring it.

    Tps checked good. o2 sensors are brand new and read right. fuel system is operating correctly

    Car has since been tuned and still has the exact problem same
