Is there any car that doesn't get horrible gas milage during accelaration?

I Currently drive a 2013 Honda Civic which has a meter in the dashboard that reads from 0-70 MPG with a 35 mark in the middle but it usually goes to 70 when i let off the gas then if i press the gas down even like insanely lightly. It goes to 15 mpg and its hard to tell what its at because it changes so much. So please help if you have any good input on the situation

Can you put in an after market radio without dash kit?

I got an after market radio for Christmas and I asked my uncle to install it he s real experienced with car and modding. I've been looking at vids of people installing the radios and they all use the dash kits. Mine hasn't came in the mail and he s installing it tomorrow so I was wondering can he install without dash kit? Is that possible (btw I'm asking not him) and it's a 2001 Honda Civic. A double din radio is being installed.

How much should a 05 Civic engine swap cost? Am I getting ripped off?

I purchased a 2005 Honda Civic (non VTEC) with a blown engine. I don't have much money available so I asked my friends dad to install it an engine for me for a lower price. He said he could do it for $800 for me and it would take about 3 days. (great I thought) I purchased an engine for $600 which ended up having a blown piston and having to file a small claims complaint with the person I bought it from. So I bought another engine for $450 and dropped it off at my friends dad s shop. After about a month he called me up to tell me that the car is done and my total cost is $1700! WTF?! $850 for labor but then another $700+ in parts that he never even called to tell me the car needed?! If this is the average cost of a swap and parts (engine mount, belts, oil change, plugs, gaskets) and nothing else major I wouldn t mind eating the bullet. But I feel like I'm getting ripped off. And to make it harder still he s my friends dad. Can anyone shed some light on the avg. Price or offer advice?

Honda Civic 9th Gen. Vibration at Idle?

I'm a proud owner of Honda Civic 2013 (9th Gen) LX 4 door Automatic.
I bought it used for 52 Thousand KM and now it has 72 Thousand KM (20000 in a year)
As a rule I leave the car to warm up in cold mornings, however I started noticing something weird.

In the middle of warming up, The car starts to vibrate the RPM drops whil vibrating, the kind of vibration that would appear just before it stalls.
The car vibrates just for a second or 2 and stops, RPM goes up again and continous to warm up.

I used to feel the same vibration when changing gears (from Drive to Park or Reverse to Park) or turning on the AC, but was very mild, however still can be felt.

Otherwise, when the car is warmed up, it is idling perfectly.

I have already cleaned the throttle body not to long ago, and cleaned the spark plugs as well.
I have took it the dealer ship to advise on the issue, and ofcourse they didn't know what was the issue and decided it was normal!

Any assistance on this regard we be great.
