          since it's freezing up in Canada..i wouldn't think it'd be a main relay issue. But it MAY be dirty fuel injectors..get some Chemtool b12 or Seafoam and add into the tank and head.

                A common fix for code 43 is to change the oxygen sensor. Strange, I know... but more than one person has said this to me. I've gotten the same code (the car sat for a while beforehand... since I've been driving it regularly, it hasn't come on... used to happen at higher speeds...)


                You have an LED on your ECU? Werd...

                    A week shouldn't do it, but who knows... It seems to be worse in the cold weather as well. The chances are that it's the oxygen sensor (though be aware of any pinging that could result from too little fuel... if it IS the fuel supply system, that could destroy your motor.) Mine cleared up, in time. I still need to replace the o2 sensor, but I'll wait until I get a header to bother with that. Replacing it would be best, but if you don't want to, drive around for a few weeks and see if it just stops. As long as the car is running properly, the worst that will happen is that you won't get the best gas mileage.

                    Does the light normally come on when you're driving about 100km/h?

                        Don't bother with premium fuel. It won't do any good on an engine that's designed for regular. Injector cleaner... I've heard mixed reviews about that... I've used it and never noticed a change, but it never hurt anything.


                        When you change the o2 sensor, which would be wise regardless (better gas mileage, healthier engine, etc...), get one from Honda. They cost more, but the Bosch ones that are available at most autoparts stores rarely work well for our cars (actually, Bosch ANYTHING seems to give most people troubles!)

                            That could be a failing sensor... I'm going blank right now on exactly where the sensor is that reads the rpm, but I believe it's read at the cam. Or it could be a grounding issue. Check your ground wires to see if any are broken. The one on the passenger fender on my car was broken, and I couldn't tell until I pulled on it.
