Thank You for reading......

I have 2000 Honda Civic 4 cyl Front Wheel Drive Automatic 102000 Km done.
when i driving my car sometimes when i'm going to accelerate after slowing down (breaking), although the accelerator pressed it will not accelerate and also the RPM remain same and the accelerator pressed further a Knocking sound comes and it will then accelerate. this is not always happen. Gradually increases the occurrence.
I performed full tuneup for the car.cleaned the throttle body and replaced the fuel filter and also spark plugs. after that it runs very well. had more power and no such abnormal sound.
but after about 3 weeks, when I'm driving a hill street sometimes that knock sound comes from the engine side. it will comes when i depress the accelerator pedal suddenly to get more power after slowing because of breaking. i will appreciate if some one help me to solve this problem.

hi,
Still the problem exits. i didn't retard the timing. it happens when driving up a hill. if i suddenly depress the accelerator. this sound comes with a little vibration.

Thank you.

hi,

now i have a doubt on this. is engine knock comes with a vibration? it happens when more torque is needed.

thank you for your help
