I've recently mentioned in other thread how my Accord seems to have seems like just a bit too much of exhaust smoke in this type of current weather in the UK. When it's 0 to 10C, my car seems to have excess smoke for first 10-15 minutes before I lose it. For me it would only seem normal if it lasted up to 5 minutes but mine smokes way longer. Is this a Honda thing because just few days ago I drove up to a traffic light and I saw same amount of smoke coming from another Honda....I think it was a 2002 Civic. Like you can tell other cars produce way less smoke in cold weather, but Honda seem to have way more of it? Is there a reason for it? Does your Accord have same symptoms in colder weather that last longer than other cars?
