    Have you tried cleaning the IACV and FITV(if equipped)? Also, try unplugging the IACV when it's warmed up.

    So I unplugged the IACV and it worked. Thanks.
    Now my other question. Would any IACV off these engines
    ,D15B8, D15B7, D15B7, D15Z1, fit a D15B?

    Yes; D15B VTEC has the exact same manifold minus the purge solenoid.

    All of the D15s asked of all have the same IACV. Only difference I notice was the rear plastic color was either black or white; but uses same connector.
