look at both banks o2 sensors if you have a leak the fuel trims will be erratic
Here is a log I just ran today, Fuel trims look ok, but o2 seems to be erratic. Does this seem to be a vacuum/exhaust leak?Quote:

Mine were loose at only 18,000 miles on the clock (no loctite on threads) and required ~2.5 turns until correct torque was reached. There were fuel stains right at the head/intake connection which tipped me off.
