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)?
Thanks very much,I will check those things

An oil leak inside the distributor can cause the engine to misfire resulting in a loss of power. It is common for the distributor to be replaced to correct this concern.
The PCM can misinterpret misfire data and set a false Check Engine (MIL) light requiring a...
My car will turn on and then shut off, have to press the gas for a little while to remain on and the check engine light is on
only when vehicle reaches 55 m.p.h. or above will check engine light go on
