99 Lexus Rx300 P1354 P0505 Misfire 2,4,6 in 99 - 03 Lexus RX300 Posted May 18, 2012 I bought a 1999 RX300 AWD with a bad engine. Previous owner took a hammer to the Front Cyl Head & Intake. Bought a Used Head, sent both heads to mach shop (valve job) & rebuilt engine. Engine runs poorly, no power at all, & sets DTC P1354, P0302, P0304 & P0306, No power at all Replaced the Oil Control Valve & Cam Position Sensor OCV Filter is Clean I thought maybe the cams in the used head might be wrong so I bought another used head off a Rx300 AWD & switched out the Intake cam, No Change still running poorly & setting the same codes. Any suggestions !!! Jay
