[QUOTE="stutaeng, post: 24017, member: 6175"] Check fuel pressure with a gauge. Not common for low fuel pressure to ONLY affect one bank, but possible your O2 sensor on the other bank is not even reporting correctly (sounds like it.) Usually low fuel pressure will affect both banks on the fuel trims, almost identical percentages. BTW, what are your fuel trims? Do you have a scanner that can read live data? [/QUOTE]
