I have a 99 rx300 with 92K miles. The check engine light just came on. I did fill up at a gas station that I usually don't use a few days ago. Auto zone says the diag. code is P1133. I believe this means the bank 1 sensor 1 is bad. Where is it located? Should I replace it right away or try cleaning mass air flow sensor or run a few more tanks of good gas through it? Will I cause damage by not replacing it right away?

We just bought our first one also. A 99. We put 2000 miles on it driving down south. 80-90 the whole way but no speeding tickets. When the vehicle is cold it takes the transmission exactly 2 minutes to warm up before it shifts into 4th gear. Until the 2 minutes it takes to warm up it drives in 3rd gear at high rpms. Any thoughts?

I recently purchased a 99 rx300, we love the vehicle. The casing on one of the remote entry keys was cracked and falls apart when you try to use it. I bought a key with the same id # off ebay. Does anyone know how to program the key I bought.
