My problem is that when I crank up my car and it begin to idle it begins to make a popping noise and when I begin to accelerate the popping noise continues until I get to about 60 mph or 65 mph and then you can no longer hear the popping sound. I changed my idle pulley and I changed my tension pulley. After I removed my belt and restarted my car with the belt off and the popping noise continued.

have a pro check this for a broken pushrod, valve spring or cam problem.
