- Bank 2 Air-Fuel Ratio Imbalance Confirm intake pop on acceleration, worse with fuel trims disabled. B2 trims are about +8-10%, B1 close to zero. Misfire counts appearing on #6 during snap test that coincide with the intake pops. Perform injector balance test, all injectors drops to 20 psi during pulse test except for #6 which drops to 24 psi. Ran test 4 times with identical results. #6 injector flow is lower than all others. Need to replace injector #6. Checked ignition system, found #6 plug heavily oil/carbon fouled and over gaped by .010" look to be original. Advise to replace plugs.
