Hey Scotty I love your channel! I have a 2010 BMW 320i (4 cylinders, GDI, No turbo) automatic with 86,000 miles. Every 2 months, I am getting a check engine light which stays on for 1 week and then disappears by itself. The fuel quality is questionable right now where I live. The codes are:
P2096: Post catalyst fuel trim system too lean bank 1 (current and pending)
P2273: O2 sensor signal stuck rich bank 2 sensor 2 (pending)
The car runs great, except for a very slight minimal rough idle (you need to stare at it to see it). And it may have lost around 20 HP because of the lower octane rating. Next week we are getting some fuel with a higher octane rating. What are your recommendations? Is it safe to drive it this way? Thank you!
Well as long as you don't push it and drive it too hard it probably won't hurt anything the oxygen sensors measure how efficiently the fuel is burning and if it's s***** fuel well you're going to have problems
THANKS!!
