Scotty, love the videos.
I have a 2000 Lexus es300 with 145k miles on it & I love it. I haven't had any issues with it until now. The check engine light came on. It's just on, not blinking, luckily. I scanned the computer and got a "P0171 System To Lean Bank 1" code. I paid a mechanic 45$ to tell me what was causing the light to come on and he said one of the 2 front oxygen sensors is not working. He told me which one but I'm just gona replace them both at the same time.
I found a good deal on two O2 sensors online but they won't be here until one week from now. I made sure they weren't Chinese rip offs that were gona break in the near future.
My question is: is it safe to drive with the check engine light on while I wait for the parts to come in the mail? I drive to and from work. It's 14 miles round trip 5 days a week.
