HI folks, A week ago, at night under heavy rains, I got trouble on the highway when the spark plug suddenly failed, the engine rumbled and the check engine light was on. The engine stopped and couldn't be started until 5 minutes. The engine eventually started and with 40 Mph I got home. The next day I replaced the spark plugs, and also the wires. The check engine light then OFF, the engine runs smoothly, until the CEL suddenly came ON again while I was commuting in town. My mileage is still 93 K. Can anyone tell me what's wrong and how to get rid off this CEL? Can I turn off the CEL by disconnecting the negative battery and hold the pedal brake for 10 second? Will it work on 2000 Mazda 626? Thanks in advance.
