The engine warning light on my 1988 Honda Civic Wagon always turns on around 30 seconds after I start the car, and it stays on until I turn off the car.  Judging from comments about this problem that I've received from other members of the hondacivicwagons eGroup, the fouled plug shown in this photo is implicated in this problem with that warning light.
     As of today (21-Mar-2002) I'm unsure of what to do about this apparently-ruined plug.
