Your engine does use a chain, as opposed to a belt, and they do tend to last a lot longer. They're not considered a normal maintenance item. That being said, most modern chains are nylon-coated, and do not last as long as the old all steel ones. But still, 95,000 would be pretty early to expect any trouble from one. And if the nylon does start to chunk off, you will notice some drive-ability problems, but not catastrophic failure like with a belt on an interference engine. So I'd say don't worry about it unless you have symptoms. If you do, you can check for timing chain slack by using the procedure outlined here;

Oops, almost forgot that the 3.3 doesn't have a distributor anymore. You can still do the test by taking off a valve cover, and watching a rocker arm instead.
