Probably wrong sequence in loosening and tightening the tensioner. You will probably need a new tensioner as the bolt on the thread on the old one is now bad. The Sticky at this Forum has a DIY section on tensioner?

All the signs of a bad tensioner. Hopefully you didn't thread the bolt out so much that you bent the bolt. These tensioners are a poor design, you can search and find tons of post on this same opinion. Buy a new one. It's a DIY with some patience as most of the bolts are pretty tricky to get to. Do a search, as QVHK suggested. There are some good write ups but I don't think there's one on the sticky...
