Incredible 2006 Pontiac G6 Check Engine Light Problems 2023. Used to get up to 34 @ 65mph down a flat highway and 26 mixed driving. Ever since then, i get a trouble code saying system too lean (bank 2).

This is a simple fix for the pontiac g6 3.9l if the check engine light is on, before buying any part i would highly recommend check those. You can read this engine code using an obd ii code reader. Web i have a 2006 pontiac g6 gt with 51000 miles.
