Hey everyone,

I’ve had both of these codes for quite a while now and looking to finally resolve them so I can get my remote start feature back. The scan tool reads them as “System Too Lean Bank 1” and “System Too Lean Bank 2”

Just wondering where you guys would start, new MAF sensor maybe?

The only symptoms I’ve really experienced are sometimes a rough idle with the aircon off, very rarely it might shake like it’s about to stall if I rapidly decelerate and let the revs drop like a rock (like it drops a little too far before recovering) and somehow…. better fuel economy…. I seem to be getting a couple more days commuting out of a tank than I did before.
