1999 - 2004 Odyssey
Hello all. Original owner looking for help diagnosing misfire codes:
Codes: P0300, 0301, 0304, 0305, 0306, 1399.
Symptoms: Intermittent rough idle, low power, struggling up even gentle slopes at highway speeds. Runs fairly smoothly on level highway. Seems to be worse when engine cold.
