Hi, everyone
I have a difference of 3-6% between my banks in different scenarios on my 2016 Camaro RS. Overall the STFTs + LTFTs are 0-10% on each bank after dialing in my MAF. I've already changed spark plugs (OEM) and injectors (OEM), and my only bet, for now, is on the timing chains
Is 3-6% difference between banks normal? If not where should I look next?
Thank you
I just generated a histogram of the absolute value of the deltas between my bank 1 and bank 2 total fuel trims from a recent log.
63% of the deltas were 0% - 3%
26% of the deltas were 3% - 6%
11% of the deltas were greater than 6%
Overall average total fuel trims were 2.25% and 3.24% for banks 1 and 2, respectively.
This is from my stock 2023 Camaro RS.
