Services Performed
- Balance and rotate all four tires
- Found code P0171 for bank 1 lean. Found intake manifold gasket to be leaking air, and intake manifold bolts to be loose allowing un metered air come into engine compartment. Replace intake gasket and tighten bolts to proper torque specs. After driving fuel trim still above 10%, found calculated load percentage only 60% at full throttle. Recommend remove and replace mass air flow sensor, also replace oxygen sensor due to age, reset fuel trim and road test. Fuel trim is at 7% after numerous test drives.
