Hi.
I have a few previous threads about detonation problem. By your helps i have almost fixed it. Thanks
So there is no more detonation during daily driving, even at higher loads.
But at high RPMs, it still knocks. At third gear. If it goes beyond 4500rpm-5000 rpm the knock sound is auidable. (But if i drive at low speed, at 5th gear, where engine under very high load, still it does not knock )
I unfortunately can't retard the timing any more, because engine likes to hesitate when pressing the throttle at the traffic lights.
I have already made some researches before posting here.
There could be many reasons, such as carbon buildup, vaccum leak, wrong ail-fuel ratio and so on.
But i wonder if its existence only at higher RPMs would give me any clue.
Engine has electronically distributed ignition.
