I have a 2000 rx300. Over a month ago I started getting a po1150 code. I have recently developed an exhaust leak directly in front of the cayalytic converter, so I did not rush out and replace the sensors. The code would pop up every couple hundred miles. Two days ago I got a po330 code that comes back on within 20 miles or so. Yesterday for part of my driving the rpms were higher than usual. I would appreciate any opinions and suggestions. Thank you.
I fixed the exhaust leak but still get both codes after driving 20-60 miles.any suggestions on tests or solutions would be appreciated.
