Carburetor Problems of Honda Civic

When engine is warm and car is at idle (either when stopped at traffic light or when parking before shutdown) and you open/close sun roof and/or power windows the rpms dip, car shakes, and engine almost stalls before rpms recover to normal idle. This has happened at least two dozen times and started happening soon after taking delivery. At approx 400 miles car was taken into dealer and dealer was able to reproduce the problem on my vehicle and also reproduced the problem on other new Civics on dealer lot. Dealer reset pcm and performed idle relearn procedure. This did not resolve the problem. Dealer reported to Honda engineering and they had no knowledge of issue and offered no advice. Additionally at approx 600 miles after car sat unused all day and when attempting to start later that night, the car did not start on first attempt. On second attempt and after cranking longer than usual for startup, the car started roughly with a jolt and ran rough (car shaking) for 3-5 seconds.

I purchased this car because it was advertised as a fuel efficent vehical. They advertised 31 mpg in city driving 38-42 highway. I have had the car for 4 months. Never used the air conditioner. Drove moderately and am getting 19 mpg. I guaged it by the number of gal. Pumped not from gas guage in car. I have reciepts and a log of all miles and gallons put into the car. The dealer tested it and said it was getting 26. 3 driving 10-30 mph. I am unable to get even that which is a substancial amount different than the amount advertised. I am dissapointed and frustrated with the performance and would like to notify Honda.
