1989 Ford F-150 mileage: 50,000. My engine knocks/pings on hills and during acceleration, but only when the engine is warmed up. Switched to 89 octane from 87 but it did not help. Engine has new plugs. Any ideas?

Check ignition timing and the knock sensor; it may be failing. It is located behind the intake manifold in the block
