turn up your idle. 3 rpm is a little low.

please if u can be more specific how to turn my idle???

I was really kidding. I assume you mean at 3,000 rpm. Your car would not run at 3 RPM.

As you asked me if you asked your question a little more clearly you might get metter more clarified responses.
What kind of fuel are you using? Is it at only 3,000 rpm? Are you sure it's knock? If so how do you know.

listen my old ECU number was MD166255 , it stopped working so I couldnt find the same number in my country so i bought another ECU with number MD169144 and my car worked but the check engine light is on so i put it on scanner and figure out that its a knock sensor.
my car dont accelerate well but above 3.000 rpm and under that it goes like a bicycle man so what should I do??????? scanner gives a knock sensor can I fix this problem without changing my ECU??????

check your heat shields and other connections for a loose bolt. These can enter harmonic resonance at a certain rpm and fool your sensor.
