Check your plugs & wires, fix the boost leak, check your timing, and do a compression test to see if you burnt up a valve.

Check your plugs & wires, fix the boost leak, check your timing, and do a compression test to see if you burnt up a valve.
A couple other things after the above might include going through your vacume lines looking to make sure their hooked up, and then to see what kind of condition they might be in (ie cracked, brittle, leaking ect...), and while your doing your compression test take a look at your plugs to see how things are running.

Ok first of all, clean up your posting (shift key). I think you solved your own problem in your first post. Boost leaks will cause the symptoms that you are describing. Fix that and get back to us if the problem still persists.
