MT fit jerking at 1st gear

is it just me or are any other fit require an extremely focus mind and feet to do a smooth acceleration? and some times even when the clutch is fully engaged at 2500-3000 RPM then i continue holding in the gas to do a low-mid acceleration, the car would just jerks . well I've been driving manual all my life and i consider myself an above advage driver. I've never owned a MT car that act the way fit does. is it because of the gutless engine? (all my previous/second car has 6 or more cylinders and would not jerk on 1st.) i work at a shop and I've driven a fair amount of cars but there is nothing else like the fit. I'm thinking it might be something with the drive by wire acting up..... i don't know. it pisses me off so usually i would just floor it to take away the jerking which defeated the purpose of driving a econo box to save gas. oh, and friends who've driven my car says the same thing. so it's not just me.

It's definitely caused by the engine's lack of torque. You just have to get used to feathering the clutch

I'm with you guys... The worst is the 1st when cold,
now you talk about jerking ! The good and the bad
news is that it's how this car is made... need to rev
high to got torque. It's a Honda thing...

It got some getting used to when the engine was cold but once it got to operation temps, it felt fine to me.

I notice it a lot when switching from driving my '89 Accord to my Fit. They drive quite differently but after a little bit you just adjust.

Exactly, MUCH worse then.

I kind of agree on the lack of HP/torque, but I have driven cars with less HP (28 and up) and did not have this problem.

What seems to happen, you rev, let up on the clutch, the car moves forward, and falls on its face..(lurch)..then catches.

I still think the idle is too low with the air on at idle, it should kick up a bit to lessen this effect?

^exactly what you said. it feels like as soon as the clutch engaged and you think you gonna move along smoothly, the car automatically cuts off your throttle and go again(X3 times when cold). that's why i think it's they way the programed the throttle to cause such problem. I've driven less power full car such as 1.3 echo with wired throttle and it didn't have this problem and maybe I'm just too used to making small adjustments with my feet to make a car moves smoothly without the aid of drive by wire computer. and when i do those adjustment with my feet the computer doesn't know how to response to the input.... or maybe just lag of torque

seriously, my 82 carbriolate with 250000 km on clock + no oil change for a year pulls harder than the fit. lol

i think you guys are either not clutch-in all the way or clutching out
too soon.

although the full engagement is around the middle of the clutch pedal's
throw, it starts engaging pretty low near the floor.

Yep. The surge in 1st/2nd/3rd gear in the Fit when the engine is cold is one of the only negative things I've noticed.

I think a lot of it might have to do with the fact that the Fit's first gear is low low low. I guess it's necessary to get the car moving from a stop with so little torque, but I try to shift into 2nd as soon as possible, and even use 2nd when driving around parking lots, etc.

After moving :

It's not the Clutch
It's not the nice 5 speed
It's the poorly designed Throttle by wire that is the cause of making it hard to shift.

With a normal design, when you lift off the gas the RPM's will drop and fall right into a spot for the next gear. With the Fit's TBW, the rpms will stay high and even pop up a tad before falling. 99% of the time, when you release the clutch the eng and tranny RPM are far enough from each other the car will lurch.

Watch the tach and start adding some delay to you time wit the clutch it and that will help.

The first gear definitely jerks. Places I notice this problem:
1) Starts - solve by engaging at higher rev and ease the clutch in
2) Speed bumps - solve by disengaging clutch while going over the hump
3) Bumper to bumper traffic where I'm engine breaking - solve by being in second gear or not taking right foot off the gas completely

Hope this helps.

I agree. I think the bad Drive by Wire system is the culprit and not the low torque issue. But, I don't think the OP was talking about the hanging rev during shifts... he's talking about the jerk in first gear at low revs.

I don't know about a jerk, but I have noticed a clutch shudder when cold in 1st gear. While the clutch is in the "friction zone," there's a rapid grab-slip-grab that feels like a warped clutch disc. It goes away as soon as the car warms a bit.

I've notice the same feeling in my fit...could anyone shed light on the issue?

odd.. in 1st gear i'm experiencing absolutely no jerking. i roll out of 1st gear lower than 400rpm sometimes and have not stalled. i can't imagine jumping out of 1st at 3k+ rpm, maybe that's the problem? i usually wait till the cold light goes out before i leave, cold engine/tranny may also be the cause of the jerky 1st gear.
