I had the same symptoms with my 99 RX300, both constant and flashing CEL, rough idle, smell of exhaust, jerking at various speeds and revs, hard brakes at idle. I was getting 2 4 & 6 random misfire codes. I replaced the left oil control valve (part#15340-0A010). The cost at the Lexus dealership was 97.46 and at Toyota dealership 92.78. The fix took about 10 minutes (very easy). The problem is solved: no CEL, runs perfect. It's definately worth a try :)
