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 !!!
