To recover, use high test if not doing so and try putting two bottles of Regain in you tank. Then drive down the freeway in 2nd gear to blow out the accumulated carbon. You should be seeing black exhaust spewing out during this run.

Carbon buildup causing higher compression ratio or hot spots. Wrong type of plugs or wrong heat range. Wrong static timing (improperly installed timing belt). Wrong ignition timing (octane jumper, Chip). Ping or rattle from these usually increases at moderate load. Plug wire crossfire can produce a more limited knock under wide load conditions. A constant heavy knock under load may be a bad rod bearing. "Those who cannot remember the past are condemned to repeat it" -George Santayana
