Fuel injector question... running rich 200

I pulled the codes last night to diagnose the check engine light problem. '89 has been DRINKING the fuel lately. It even smells like a gas station. Codes read fuel injector problem, compensating for rich mixture, and compensating for extremely rich mixture. I am going to test resistance tomorrow night, but all the injectors sound like they are working through the stethascope. Has anyone had any luck sending injectors off to be sonically cleaned and "rebuilt"? If so can you recommend where?

Has anyone had sucess with the dealership cleanings?

The car has around 175K on it. What is the "normal" service life of these injectors? Would it be worth the cleaning? I would prefer to not spend the cash replacing them.

I have already changed the fuel pressure regulator.

Thanks
