This wont do any damage to your engine until you have an accident making a mistake with the pedals:) The IAC would only doing the same function that you are doing manually. I do think you have more of a problem than the IAC being faulty, since it should just add extra air when you switch things on like the lights, air con etc. Maybe your throttle ...

Your car may have plastic guards underneath to stop water from spraying up on sensitive components, but everything under the hood is typically waterproof to some degree. That said, the only "damage" I have ever seen is the spray of water loosening or tearing off plastic guards that are not properly fastened or half-way ripped off already. The basic short ...

Bit of transmissions 101 First gear makes the most torque / power, but has the lowest top speed and worst fuel economy. Top gear has the highest top speed and best fuel economy, but the least amount of power and torque. In an auto, leaving it in D is fine 99% of the time unless you need more power. Shifting into 3, 2, or 1 typically limits you to that ...

It's Fl├╝sterasphalt (literaly whisper asphalt) @DucatiKiller has already given a nice answer about a concrete version of this, however, this is really asphalt and is also processed more or less like standard asphalt (Lots of heat etc.). The one and only reason why this is used here in Germany is to reduce the noise of the wheels on the road, and it really ...

Although I am unsure of the material that is being used for the roadway in your photos it appears similar to Topmix Permeable concrete You asked Can anyone explain how new pavements achieve this remarkable performance at eliminating splashing? Response Topmix Permeable concrete is simply a very porous concrete interlaced with large rounded pebbles. ...

"Blipping" the throttle just means giving it a very short (half a second) stab raising the RPM for a short time. It creates smoother down shifts because it raises the RPM to where it's going to be after the shift so the synchros have less work to do.

I had a buddy years ago who liked to do the same thing. Our big plans were cut short one evening when he hit a good sized puddle and managed to knock his muffler completely off. It was surely loose before, but it would have been nice to repair it some other time. It certainly won't help anything. If you splash pedestrians, you won't win any friends, ...

As HandyHowie said, this won't cause any damage. However, there is a better way, based on the assumption that you have a foot on the brake because you leave the car in D at the lights. If the car will still idle in N with a bad IAC, select N as you're coming to a stop and put it back in D as you press the gas pedal to set off again. Make sure the revs are ...

I have a 2013 Honda Civic EX Sedan. The ECON mode, from my research and personal experience with my car, does the following: changes the shift pattern of the transmission to maximize mpg by limiting downshifts unless you "floor it", reduces the A/C compressor operation and A/C fan to conserve mpg, changes the throttle response to maximize mpg and adjusts ...

There is a very simple answer. The friction co-efficient on the paint lines is lower than the pavement. It's pretty common on almost any paint line in any state within the Union. That being said, some road racing governing bodies like the FIM and FIA force circuits to use a particular type of paint with grit in it that has a higher friction co-efficient ...

The stalling symptoms could be explained by a fuel pump relay that doesn't like heat. I say this because the vehicle stalled seemingly intermittently, but whenever the car had been running for quite some time, only for it to start up again after a few minutes (allowing the relay to cool down a bit). If the relay is the root cause, the fix would be to ...

I drive a 2014 Civic EX coupe, automatic, and about a week ago turned the Econ button off... the icon light on the dash turned off. I bought the car several months ago and it didn't occur to me until now to try this. Performance has been about the same, but my mileage has actually INCREASED 3-4 MPG! Go figure.

In a properly maintained fully functional manual transmission equipped automobile, I prefer to be in neutral with my foot not on the clutch pedal. The reasoning is that if I happen to be rear ended or something, there is no way for me to accidentally take my foot off of the clutch and roll out further into cross traffic.

There are a number of factors that could contribute to this happening. Improperly inflated tires If your tires aren't inflated correctly for their size and the weight of your vehicle they may not have a proper contact patch with the road. Very Soft (sport) tires Very soft tires are great for gripping a rough surface like concrete or asphalt. They kind ...

The only real world difference between a sedan and a hatchback is the added trunk(weight) and in some cases a longer wheelbase in case of a sedan.(Not counting Looks obviously) The above difference doesn't define the driveability of the vehicle on snow. To drive on snow a AWD drive system with traction control and higher ground clearance is all that's ...

Do a search on google for "torque power graph". These graphs plot torque and power against RPM and each engine design will be different. From a graph for your engine you would be able to see which RPM produced the greatest torque. You may be able to find specs for your engine specifying maximum torque and the RPM where this is delivered.

In a manual tranmission car, the clutch is 'meshed' only when both sides of the clutch - the engine side and the wheel side - are running at the same speed. Downshifting Example I'll make up some numbers for an example: Say you're at 3rd gear, going 45 miles an hour and the engine is at 2.5k RPM. If you downshift while still going 45 miles an hour, the ...

This could work in a car with an open differential and an active traction control system. When the system detects a wheel spin, it actively brakes (and locks out) the particular wheel, as a consequence the torque is directed by the differential to the wheel with traction (least resistance, as you noted). I do not know the details of the implementation in ...

Wet brake pads don't stop as well\quickly as dry ones. I remember this as more of a issue with drums vs discs, but I still always hit the brakes lightly after a puddle to help them dry. Also if you have any tire problems already (say a weak spot on the side wall), the shock from the bump may be enough to make the weak spot into a blow out. But ...

When you say "stopped dead in its tracks" I assume you mean with the wheels spinning. In this circumstance your choice of gear selection in an automatic is pretty much meaningless. What you generally want is less torque to avoid wheel slip. In a manual transmission you could use a higher-than-normal gear to some benefit, but such a feature is generally not ...

I cannot know for sure, but the new pavement may be more permeable than the old, allowing water to quickly drain directly through the roadway, rather than collecting on the surface and having to run off the sides. See this video for a demonstration

If you have just been doing some heavy braking, making the discs very hot. Cooling them very quickly by driving through water could warp the discs.

I think this is an urban myth. Take for instance a BMW S1000RR. This motorcycle produces 179 rear wheel horsepower. If you held the throttle at peak torque and launches you would either. Loop the bike and land it upside down. (top of gas tank hitting pavement) Burn up clutch quite nicely getting to the speed where you could engage it and rip a wheelie ...

It very much depends on the specific vehicle and more so on the type of tyres fitted. As a side note, my old Lancia Delta HF Integrale 16V rally car (a hatchback) was brilliant on the snow whilst my fathers Lexus IS200 (a saloon) was awful.

It doesn't really matter. Everything else being equal, the car with the most neutral weight distribution would perform best in snow. I would even think that the car that has the bulk of its weight up front would be least inclined to skid or overstear. Usually, that would be a hatchback, but in these modern times most vehicle manufacturers build their cars ...

Your tyres are probably way too hard. Either because their "energy savers" or because they're very old and are starting to perish (your first clue is tiny cracks in the side wall and/or little shiny spots).

In my 2014 Civic the ECON button is most efficient when driving long distances. When driving distances longer than 30 miles I average 37-40mpg with it on versus approximately 33mpg with it off. I'm a daily driver of a minimum of 50 miles per day and definitely notice a difference with the ECON on. I agree that it does make the car a little sluggish but if ...

Hi folks I just picked up 2015 civic with this Econ button. Just to check how effective this is I used it with couple of full tanks and couple with Econ switch of and I always fueled from the same gas station. The result is this Econ does not help you at all in fuel economy I drove from home to work and back and no other use of vehicle. It gives me the same ...

Great page. I just bought a 2016 Honda Pilot Touring 2WD and have been playing around with the ECON button along with the Idle-Stop features. For those not familiar with the Idle-Stop feature, when the car comes to a stop, the engine automatically shuts off to conserve fuel and improve fuel economy...and the engine starts up when the brake is released. ...

I've turned it on, and turned it off. I notice virtually no difference in performance or fuel economy between the 2 modes. I get consistent 37-38 mpg in either mode and the air conditioning seems to run the same in either. No difference in acceleration or any other differences. I personally think it is a placebo. It's a 2015 Civic LX.
