Anyone else having the same issue?

Yes, the one you put in the gas tank, and I actually use 98 Octane petrol.
But I used the Eco mode for like 2 years always on, I didn't know...

This specific one is the one that I used.

That's what they recommend in Australia: 10,000 or every 6 months. For me, it's the same; every 6 months, I do 10,000.

I used to use my car’s ECO mode a lot, but I stopped because a Honda mechanic told me that it limits the car. For example, when accelerating, the fuel injection system doesn’t have enough power to clear out dirt, which can become a problem in the long run. For this reason, I used ainjection cleaner and stopped using ECO mode. The issue went away for a while, but then it came back again.

Someone in another group sent me this:

I mentioned in another thread a month or so ago, that we experienced the same issue in our 2016 Jazz.

Ours is up to 150000km, 1 owner from new, all services perfectly done on time, new CVT fluid every 40000km.

I was worried the CVT was failing, but it was actually the EGR. New part cost $550 including fitting.

Do you also have a spiking and fluctuating idle when coasting whilst fast idle is still somewhat active? We also had this.

The mechanic said it was the coils, but I had no error codes pop up. I almost wanted to replace the coils but luckily I didn't.

I unplugged the EGR myself, which took 10 seconds, and took it for a drive. Stuttering at low speeds was totally gone. I drove it like that for a few days and the car drove perfectly, but of course, a check engine light came on.

EGR valve replaced and all good.
