Yes, the little shock absorber for the belt tensioner can make an irritating rattle. When I replaced mine it was due to the bushing on the alternator side being worn out and too much play. Replaced the shock and no noise.

But, I would also take a hard look at the belt tensioner to make sure it is functioning properly and not defective. These things happen sometimes when they are loosened and re-tightened. The rubber bushing goes bad and tears.

Hey Zak, did you ever find out what was causing you full throttle problem?
