    P1164 is a code for problem with the air/fuel ratio sensor performance. P1259 is a problem with the VTEC oil pressure switch circuit or oil pressure valve circuit. P1164 , at this point could be the sensor , but could also be the PCM. P1259 could be from running low on oil or clogged V-TEC screen. ALSO could be electrical or other internal mechanical problem. .......Are you ALSO getting P0301 and P0304? Does the P1259 clear with scanner and stay off until you try to rev over 4000RPM (when V-TEC kicks in)?
