So I have a Civic 1.4 type S and I hadn't noticed this when buying the car as the test drive wasn't very long. But once the engine is nice and warmed up, everytime I come to a red light and stop, the car reaches it's normal idle, but then just drops to about 500rpm before catching itself back up to it's normal idle. This has been really bugging me as I am unsure what it is and the fact that it doesn't happen everytime. The car feels like it's about to shut off essentially, but doesn't.
Also I'm not sure if this is normal but when I'm in 6th gear and doing 40mph, the revs sit at about 1900-2000rpm and this wasn't the case with my previous car. Although I'm not sure if this is because the other car had a much larger engine being a 2.0L BMW.
Also when first purchasing the vehicle and filling up a tank of fuel, and resetting the trip, I was getting terrible fuel mileage, I was averaging 21.5MPG and I got through half a tank of fuel only covering 120miles.
After having a full service the MPG has gone up to 26, but I feel this might be normal seen as I use the car for very short journeys, and the fuel needle has barely dropped after covering 50miles.
So if anyone has any knowledge or understanding of what I'm experiencing, I'd love to know what the issue could be.
