I've had my 2020 Accord Sport 2.0T manual transmission for about two months and have put a few thousand km on it. I have noticed that under some conditions, the acceleration is a bit... lumpy. An example might be, moderately heavy throttle, approaching 3K RPM, going up an uphill highway ramp. It's not terribly intrusive, just odd. It's like an erratic surging feeling, like the car is being bumped as it accelerates or as though it's skipping a bit.

The first thing that came to mind was that with regular gas, the car might be preventing detonation/knock and that it may be smoother with premium gas.

It might be your traction control kicking in. Turn it off and see if it repeats itself. Go to the same on-ramp and try to replicate it. Mine does the same thing when I have traction on.

Edit: Read the bottom part of your entry and you're using regular gas? Use premium for a few cycles and see if you feel a difference. I've never messed with regular gas, it was always premium for me.

I'm not gonna get into the whole regular vs premium debate, but I am curious - have you done anything to the car, or are you running a stock Accord?

from what i can tell so far it seems to be just the nature of the beast. you have 10 gears and a computer that is doing it's best to get good MPG no matter if you are in econ or sport mode.

Manuals come with 6 gears...

Interesting, thanks! Will try both of those things.

Keep in mind that heat and humidity do affect how a turbocharged engine behaves and can lead to heat swamp/jerk acceleration. With how new your car is this is likely what you're noticing.

It could also be an issue with fuel injectors, but it's unlikely since your car is rather new.

I debated trying premium for a few tanks to compare. Yes I know it's built for reg but I also know new engines have knock sensors and other stuff that can "detune" a engine. My buddy has a 2021 GT mustang and it's only "requires" reg but he said it runs a lot better on premium.

Love that guy...and love him more for agreeing with me lol - you DO NOT need premium for a stock 10th gen (like OP's ride).
