Question to 6-speed manual owners

Kris05TSX · 03-30-2005, 10:13 PM

I picked up my car a few weeks ago, and have racked up about 600 miles so far. My question is, when in gear, say 3rd or 4th, and you let off the gas completely, whenever I go to roll back on to the gas, no matter how slowly I start to apply the accelerator, it seems like there is a hesitation before it jerks back on the power application. It's very slight... I've pointed it out to my friend while he was in the car and he thought I was crazy, but I can feel it. I'm thinking this may be a delay in the drive-by-wire throttle system. Are any of you guys experiencing the same thing?

i know what you mean! I was thinking and thinking about this one. But the truth is, there is probably no way to fix this unless you shift into a higher gear or lower gear. basically when driving and unletting the gas, the engine seems to disengage; upon the letting of the gas, the engine jerks just a tad due to engagement of the engine with the transmission. I believe that this is very normal. It has happened to me in my other cars as well. So i wouldn't sweat it. by the way congrats on your new car. any mods coming soon?

Yea, its there. Its a "feature" of the car. I've taken my TSX in for this. Apparently, the fuel injectors turn off when coasting. Getting back on the gas causes them to turn back on of course, and causes this "jerking" of the car. One of my biggest pet peeves.

And they dont plan on doing anything about it from what I understand.

You can get rid of this "jerkiness" by giving more throttle and easing the clutch out. You will adapt your driving style to the car in time and driving the car will feel more natural as a result (I hope).

Not what he's talking about.

Take your 6MT, get up to maybe 40MPH in 4th. Now, let your foot off the gas so you just coast. Now VERY LIGHTLY apply the gas again and let me know what you feel.

The car should jerk...Has nothing to do with using the clutch.

I have the same "feature" too. I've just learned to either down gear (if i have to slow down) or let off the gas, but not completely...i just feather it. So far, it has eliminated some of the "jerkiness"...at least its not as much as before.

I have also pointed it out to friends who drive stick (when they are in the car with me), they also thought I was crazy...i think b/c we're in the driver seat we can feel everything.

I dont understand why I didnt feel this when I was test driving...i guess with the rush of testing it just zoned the jerkiness out. *shrug*

I thought this type of behavior was due to pressing the gas pedal down while your at a low rpm. do the same thing in first...second or third...probably happen again.

What would happen in this instance if you pushed the clutch in (after you let off the accelerator to coast), then as you went back onto the accelerator, you eased into the gear a bit using the clutch (kind of like taking off from a stop).

We have been talking about this in another thread on the Drive by Wire throttle. You have to have slight amount of pressure on the throttle BEFORE you release the clutch. I took my car in for this too and the mechanic just slips the clutch. The way he was doing it, my clutch will last 20,000 but Acura doesn't give a flying _ _ _ _ about this because they won't warranty the clutch anyway. After some time, I have finally been able to minimize it but if you forget, the hesitation can be pretty violent. I was trying to get out of the way of an 18 wheeler coming at me at 75 MPH so I mashed the throttle and when I went to go into second, I almost went through the windshield, then got pushed back in the seat when the engine decided to come back to life. Give it a try. I still think if enough people complain, they might decide to do soemething about it. I'm skeptical because it seems that Honda thinks that everything they make is perfect, so the problem is not with their car, it's with us, the drivers. Of course in my 21 years of owning 7 different manual cars, I have never had this problem before. Go figure.

I did what you said and tried to feel the "jerkiness", but I didn't feel anything unusual. The car pulled a little as the gears engaged again, but that's a normal sensation when driving any car (in my experience).

Now, I have felt a hesitation when accelerating from first gear to second gear, but I have been adjusting my shifting habits to eliminate it.

Maybe they made changes in the 05, I dunno. But like I said I took mine in and had a Tech ride with me and he noticed the same thing...

Thanks for everyone's input... at least I feel a little more comfortable knowing that it's not just my car, but a 6 speed manuals. Just in case anyone is wondering, I have been driving a manual for about 10 years now a 91 Accord (when I sold the car, still had the original clutch with 218k miles!), and a 99 Civic Si, so it's not that I don't know how to drive... I'm sure everyone that understands the "coast and jerk" knows how to drive too. Sure, you'll always feel the power come back on in any manual, but it just seems more pronounced in the TSX for some reason...

Yea, but usually a coast and jerk will happen at a higher RPM. This happens at like 2K even 1500 RPM.
