Car slows when foot off the gas to coast
 

What makes you think there is an issue?

that normal for any car, try do it on a bike and you will see it slow down much quicker than car. its just physics...

lmfaoo, THIS

You do realize that is what is supposed to happen, don't you? Try this, take your foot off the gas, then downshift to 4th gear, then to third; the deceleration will increase each time you downshift.

I believe you just answered your own question with this statement... :dunno: Of course the car would slow down at a faster rate if you are in a gear, as opposed to being in the neutral position...you just said it, "engine braking".

Check the brakes. Sticky calipers could slow down the car while coasting

He said the car doesn't slow down in neutral; definitely not sticky calipers.

I thought this too until I read this:

n this case it's engine/transmission load braking and not necessarily just engine braking. When you're in neutral, you remove the load of the transmission gears and the engine itself




Long story long, it's normal..

If it bugs you, try applying a very, very slight amount of pressure on the gas pedal. You'll still eventually slow down, but I've found it seems to stop the downshifting from happening too prematurely.

I know what the OP is talking about. It's a deceleration that is sort of like a jerkiness to the transmission when your foot is off the gas pedal. It's normal for this car.

could it be Honda's grade logic he's referring to?

:facepalm:

The next question in this thread will be, "How come when I push the gas pedal to the floor my TL accelerates way faster than any car I've ever had; especially my Corolla? Is that normal?"

:snicker:

"I ran out of gas and can't start my car and have yet to fill it up. It turns over like it wants to start but do you think I have a spark plug issue"

When you let off the accelerator the throttle body closes creating negative pressure (high manifold vacuum) which the cylinders have to work against. At that point the wheels are pushing the engine rather than the other way around so naturally you get a drag effect which slows you down faster. If you put it in neutral, the throttle body opens just enough to allow the engine to idle without restriction while the wheels rotate freely.

That's one of the huge benefits of a manual transmission (though you can do it with an auto, just not as easily). You can downshift quickly causing significant engine braking due to higher RPM's which helps keep traction when the tires are slipping. It's saved me on more than one occasion. I've done it in an auto as well but it's not nearly as responsive.

:pofl:

This is completely normal operation of the Acura Grade Logic transmission software. The ECM keeps the transmission in a lower gear to use engine braking.
