noise when i half throttle ?

[altong0840]

recently my integra making "dadadadada" noise when i revl it abit from 1500-2000
and it feel powerless. the noise will appear till 4000 or higher rpm.

but the "dadada" noise do not appear when i pedal/ full throttle it from 3000-4000rpm.
and i feel the power and takeoff so quick.

i checked my plug/leads are good, the fuel filter replaced, the throttle body cleaned. engine oil filter changed, and the noise still appear.

is it sound like valve clearance need to be done?

nono it sounds normal when idle.and the spark plug and injector running 100% fine

[Bludger]

yea~ it is like the spark sound.

I think EKVTIR-T is correct.

might be pinging.
need more octane rating

or

less advance timing.

Did you recently put a different petrol? A lower octane one?

Is the car totally standard or got mods,ecu/chip?
