my car has a loud knock noise like it has a bad rod but if i am driving about 28to30 mph and lightly hold down the gas the noise seems to go away i was wondering if there is a common problem with this or if there is something that might ring a bell also was wondering if there was someway to tell exactly what it is whether it is a main bearing or a adjustment to the valves or replaceing the lifters etc any help would be appreciated thank you.
