    Need smog advice from failed numbers.

    Tried to get my car BARd and failed. My visual is good minus the K&N air intake which I can just switch out for stock.

    However, my numbers were pretty high! I was surprised since the head was just rebuilt. What can I do to lower them???

    ------------------HC -------------------------- NO
    --------------- Max---- Meas-------------- Max------ Meas
    (fail)15mph -------114----- 155 ------------ 785 ------- 1597
    25mph ------------89------- 70 --------------724------- 567

    What can I do to pass?

      Try some BG44K and the pass emisions test in a bottle, crank down the A/F screw for the test. Vacum leaks anywhere?,
