    Tried to pull kore codes but get nothing. I can pull koeo codes. get 511 and 565. It was working yesterday,(trying to figure out code 172) cleaned the o2 sensors cleared the codes by pulling the jump wire when koeo starts. The car now spits, sputters and no power. Cleaned mass air. My car has a 347 2.02 rpm heads, holley system max intake, and long tubes.

    You may have destroyed the O2 sensors by trying to clean them. It may be that the 172 code was correct and you were/are experiencing a lean condition.
