braking down is something we wanna avoid

what TS meant was when foot is lifted off the throttle.. NOT braking, NOT free gear.

Any 1 could help me out?
I had change a lot of things.
Fuel filter
Plug
Cable plug
Distributor cap
Rotor arm
Fuel regulator
ECU

The shake symptoms occurs mostly around d 2nd n 3rd gear in 1800 to 3000 rpm.

To help us help you better, it'll be better if you could elaborate more on the issue.
Where do you think the vibration is coming from? Is it the Engine or is it the chassis (suspension, tyres, brakes). Does the steering wheel vibrate? if not, it's nothing to do with the driving wheels or the suspension. Are you able to post a video?
