Shudder When Accelerating at First

I always use Eco Mode. I have a very light and moderate foot. I drive fairly slowly as a general rule. That's just my style. When I start out from a stop, there is a shudder when accelerating past about 15-20 MPH or so. I've tried taking the Eco Mode off, but then the whole throttle response changes and it's difficult to make a comparison. I'm quite used to the response in Eco Mode when accelerating gently from a stop. Anyone else notice this uneven behavior?

I sometimes get a shudder as well. I took mine off economy mode and started using premium fuel and really pushing the engine pretty hard for the past week. It seems to be driving even better now.

I am curious to see if the weather impacts me. I used to notice this behavior more in the winter.

Are you still driving hard now? What's the rationale behind using premium fuel. Years ago I was told that it's good to step on the pedal and clear things out from time time, especially for a car that's driven gently. I had all but forgotten about that.

I've had a lot of exotics over the years and the above is called an Italian Tune-up. I think it's supposed to clear carbon build-up. I'm guilty of driving "too easy" on my Fit so I thought I'd mix it up a bit and really get her over 4K RPMs this week. I might put her back in economy mode tomorrow and see how she drives. I might have to add one of those catch-cans if that's supposed to help these DI engines.

I'll be interested to hear how things are when you return to Eco Mode and lower revs.

Have you ever noticed at what RPM this is occurring at? (Am assuming the automatics have a tach as well....) If it happens around 2200 RPM, Honda apparently feels this is "normal" … I have a manual, I just accelerate in each gear high enough so that when I upshift, I'm above 2200 RPM when I hit the next gear and never notice it (other than in 1st) ...of course, your situation might be something different, but, just putting that out there.....there've been other threads on here about the hesitation/jutter around that RPM point. Hope you get it sorted

Although Iíve not looked at the tach, it only occurs at the speeds mentioned above and not again.

I get the shudder only when making moderate pull-offs, like merging into low moving traffic, or trying not to jerk the wife's head off on launch. Will usually just go ahead and shift and blip the throttle a couple of times. Haven't figured out the cause.

I tried driving with Eco Mode off and my initial thoughts are that the shuddering only occurs with Eco Mode on. I have a very gentle and moderate foot, and this has caused me to notice slight hesitations etc in some of my previous cars at times. My summation: R.I.P. Econ Mode
