i've got a civic coupe vti (b16) and when i accelerate hard there is a loud clunking noise coming from the front somewhere but if i accelerate hard again there is no clunk until i brake hard and then again when i accelerate so obviously something is moving back and forth but has anybody got a clue as to what, its done it since i got it and have changed a lot o bushes since but it still does it, it dont seem to affect the car in any way except that its anoying me.
