Do you have any idea about this issue to resolve this?

Hi All, @GayanR @Davy , many thanks for your valuable feedback. Yes rear shocks are good. Almost all bearings checked except inside in the engine. Can this happen due to a vacuum leak? If yes, what are the suspected areas? Does anyone have this experience before?

Thanks for the feedback. It's not a engine vibration, it is something shake/shuttering. It feel like shake whole car. Mr. Dhammika from Cotta rd did full scan while running the vehicle. Also checked ignition coils. One of another mechanic removed the fuel pump and checked it. The only thing is remain VVT sludge.

Thanks Dave for the feedback. Yes wheel balancing and alignment are done. Car shakes acceleration between 20-40 kmph and hard acceleration between 60-80 kmph. few weeks back I had to replace front caliper kit due to a break bind. Mechanic replaced both side of "front Gediya" and it includes genuine break pads, hub racer and disk. actually it is cheaper than buying a brand-new caliper kit. Copied from my original description "Also I found same shaking issue around 2000RPM in N and P gears. But mechanics says these are two different issues. But I feel these two are same issue." Have you noticed this? Cheers Heshan

Thanks for the feedback. Since you asked I checked again. I found same shaking issue when hard accelerating speed between 60 - 80 kmph. few weeks back I had to replace front caliper kit due to a break bind. Mechanic replaced both side of "front Gediya" and it includes genuine break pads, hub racer and disk. actually it is cheaper than buying a brand-new caliper kit.

I'm using this car since 2016 and this issue wan't there when I bought it. This started suddenly little by little after a two years back. However the only parts I replaced are, all three mounts (Toyota Genuine) and I didn't do anything since I bought this car except general services until this issue started. The mechanic changed the gearbox, but the issue wasn't resolved. Gearbox replaced by Sampath motors. Also I visited Mr Dhammika (Cotta rd), he checked ignition coils and full scan. The only issuehe found was the temperature of gear oil is little bit higher than normal. This is why mechanic decided to replace the gear box.

I use Mazda Demio
