hello,
last week i have installed a new ( used ) engine for my honda accord 2003 2.4L .
after driving for 10 minutes, I had a problem, it cuts off and in scanner i read this :
<<P2646 : Rocker arm actuator A, bank 1 - performance problem or actuator stuck off - Honda: VTEC Oil Pressure Switch Circuit Low Voltage>>
and the engine burned 2 quartz of oil in 5 days !!! i replaced the VTEC Oil Pressure Switch, but i had not a good result.
so I replaced again the engine. and I had the same problem, and i replaced the VTEC Oil Pressure Switch, but i had not a good result, in addition I have now two new codes :
<< P0011 :Camshaft position (CMP), intake/left/front, bank 1 - timing over-advanced/system performance Honda: Variable Valve Timing Control (VTC) System Malfunction >>
& << P0507 Idle speed control (ISC) system - rpm higher than expected Honda: Idle Control System RPM Higher Than Expected >>

so do you think that the mechanics made something wrong in wires ? or what could it be ?
thank you
