Is just changing the nozzles a good idea? Metro Fuel Injection has complete rebuilt injectors for ~$40. Why put new nozzles on worn out old injectors? The springs and all the other guts will still have 150K, 200K, 250k, etc.

The nozzles and springs are the moving parts inside the injector. The thrust pin, spacer disk, shim and upper/lower halves don't really wear out. TRUE you can have a spring go bad or break but the part that wears out by design is the nozzle (body and needle.) Some people DO replace springs but the FSM doesn't list it as routine maintenance. It's covered in 07.1-6712 if you have the CD.
