Re: '99 civic emissions problems
I had the cel blinking like that ran the codes and it came up misfire cylinder 1 and cylinder 2.
Pulled the distributor housing off and saw a few drops of water. Cleaned those off, then sanded down the contact points and reinstalled. Also my air filter was a little wet so I dried it off with a hair dryer.
This is all because of the massive rain we got here in San Diego over the last week, I drove through some 1 ft deep flooded roads and thought flooring it would be fun in the water, all that did was splash tons of water up into my engine bay.
Try checking your ignition components next. Distibutor cap, rotor, plugs, wires, and spark plugs.
