UPDATE:
Since my last post back in September, I'd been running the RX330 on 91 octane gas and diligently keeping my eyes on the dash for any of those 3 lights to turn on.
Luckily, they never turned back on!
So, a few days ago I took it to the local Rocket Smog for a smog check, as this month, as previously stated, my tags are due. I crossed my fingers, and I passed!
*whew* ...well, I guess I'm good for now...
