Clicking Sound during acceleration

i have a 94 3.4 and it makes a clicking sound or rattling sound when i rev it up or accelerate. I thought it may be the plugs or wires but i replaced them and it still does it. any help at all would be very much appreciated. thanks

is it a knock like a rod or ...loud? Lifter or something enternal maybe?

i fixed it today actually, i removed the belt and cleaned it off along with the pullies and everything works fine now. thanks for replying though.

Yea, Sorry i couldnt help!
