Hi guys, im new to honda fit world..

we just bought this honda fit 2010 80000 km.. had a problem last week with a misfire on cylinder no 1. Took the car to my friend garage and changed coil pack. At the same time i changed all my spike plug. I noticed that when i accelerate and brake my (average fuel consumption per litle) is pretty high. What you guys think about this? Its this something common on those car?

That is just a mileage per gal or liter gauge. It will typically decrease quite a bit under acceleration/uphill, stays stable at a cruise/level ground, and increases when coasting or downhill.

It's primarily a visual aide to help you figure where you are losing efficiency. Based on your video you are in an Automatic? Since I'm in a 5spd/Manual trans, I see it be steady longer and go on the "high" side since I can actually coast or be in neutral unlike the auto trans. So that may be a big difference as well.

 

The Fit will get excellent fuel economy on the highway.
City traffic, up hills, cold weather, not so good. Montréal has all three.

 

Calculate your mileage by tankfuls at the pump.
See what your real average per tank is...

I wouldn't react to what the gauge seems to be showing you for any momentary move.

If you have a "problem", your month to month, tank to tank average will be low.
Otherwise, yes I think for most vehicles, acceleration results in lower gas mileage. The efficiency of the engine doesn't really kick in until momentum is created and reached.

I'm not going to go as far as to say you don't have a problem. But I will say I think the best way to determine it....is by a bigger picture evaluation of your actual gas mileage.
