if you have a broken stud in the manifold, more than likely what you need to do is remove the air cleaner assembly, the wheel splash shield and the heat shield 1st. then remove the 2 bolts at the collector and the 6 or 7 bolts holding the manifold to the engine. once they're off, you may be able to grip it with some sort of vise grips to remove it, make sure to spray all the bolts with PB blaster before you start and let them soak to make the job easier. you'll more than likely need a new set of bolts and heat shield. check the flatness of the manifold with a straight edge to verify it hasn't warped, mine was severely warped! it's usually like $20 to have it machined at a machine shop. while you're at it, get them cermakromed while they're off!
