  1. I have a 99 Lexus RX300. Car was running fine. Suddenly, CEL appears. Very rough idle, smell of exhaust when it is idling rough, hesitation, and at random speeds engine cuts out like you turned it off and then speeds up again. Codes are P0505, P1354, and random misfire codes for 2, 4, and 6. Car seems to run fairly normal until engine warms up. Removed OCV and cleaned. Connected it to a battery pack and it seems to work as it should( but I dont know what normal is). Should I rule out the OCV and look elsewhere. Could it be the idle control valve. Any help would be greatly appreciated.
