bump up. Im going in for an oil change in a couple days and Im going to voice my complaint about the DBW and the jerkiness in first gear.

 

There's nothing they can do about it.

 

Yea, but it dosent hurt to complain about it. I still think its a problem and it shouldnt be accepted as just a "characteristic" of the car. The more compliants, the better chance of Acura doing something about it.

 

Acura as a whole could do something about it. I think its important to give them feedback so they can know what issues the car may have.

 

 

when you guys are cruising in gear and let go of the accelerator, and then press again, do you guys get a weird and light squeak sound along with the jerk?

i can only hear this if windows are open and sounds like it comes from under the hood or tranny...is this normal?

 

Sorry to bump up a REALLY old thread, but does anyone know if this throttle jerkiness in the TSX manuals was ever resolved? If so, is there a TSB?

 

My 06 makes a pretty jerky transition from no throttle to part throttle - always has.
And it's noticeable using the cruise control too. The vehicles in my garage with throttle cables are much better. And an automatic transmission smooths out all kinds of problems. Basically, I think Honda did a crappy job of programming the computer.

 

Agree. I've had an Alfa Romeo and VW both with DBW throttle and they were both smooth as silk - no jerkiness in any driving conditions.

I was kinda hoping Honda had released a fix for the manual cars' throttle issues.

 

Couple of thoughts:

1) The injectors are off during no throttle situations until RPM drops below 1000 rpm.

2) I have very little problem with the "jerks" people complain about, but I've driven manuals for over 30 years now. Feather the clutch on release to match with the increasing rpm's, staying on the throttle slightly and it'll make a smooth shift.

3) Remember to double clutch if you're gonna skip gears, up or down, as Honda/Acura syncos don't like skip shifting. We found that out when a TSB was posted on synco issues that instructed the tech or advisor to ride a demo with the customer and note if they skip shifted so they could deny claims. I mention this becuase damaged syncos can cause jerky shifting, especially between 1-2 and 2-3.

My 06 has been like that for so long that I got used to slipping the clutch to try and make it more smoother. Although I hadn't been seeing any check engine lights, I had been reading posts about failing APP (Accelerator Pedal Position) sensors that had similar symptoms. I figured that perhaps my sensor wasn't failing enough to trigger a code, so I decided to replace the sensor. I no longer have any part-throttle issues. Apparently at certain part-throttle positions, the sensor goes crazy and tells the throttle body sensor false readings. For example, if you were at 5% throttle, the sensor might flicker wildly between 0 and 10% (ie: random readings), which caused jerkiness (for me). The jerkiness is gone, but since I'm so used to it being jerky, I still find myself trying to adjust myself to try and avoid the expected jerkiness.

On a side note, I adjusted the throttle cable before replacing the sensor. It helped a little, but the jerkiness was still there (slightly). My throttle cable was stretched, though, so I replaced it at the same time as the sensor.

 

Wish mine had a throttle cable instead of DBW. :-(
