Ok in my 94 sc when i get to about 60 mph i usually hit the cruise control and let off the gas. Well i can sit there and watch the spedo drop to about 55. Then in about 30 secounds later it picks up to about 58 and holds steady. Now i am not even sure how they work i am under the impression that it may be vaccume operated. So i automaticly believe that it is a vac leak somewhere. Any input on this would be great. I also have another question. All three of my idle tensioners make a loude squealing so i checked them i believe the bearings are going out so i was wondering if anyone knew of a place to just get the bearing and the pully cause the tensioner is fine. Thanks for any input

All sorts of options. If you go to the auto parts store you can just match up your pulley. Some aftermarket units will not allow the use of the dust cover. But they use a bearing design that doesn't require it.

Dayco #89007 around $15 each. 76mm diameter and will fit properly. Is a bit narrow, but it works just fine.

Dayco #89016 around $20 each. 76mm diameter and will fit properly. Is stock width though requires a 7/16" washer to space out the dust cover if you wish to use it.

If you want to add a little bling there are a couple vendors selling billet pulley's that are quite nice.
