Update on SES Light
Well, took my car in 10/16/12 and picked it this afternoon. After a week of diagnosis, they ended up doing a couple of things:
Replaced all fuel injectors
My car was running lean so they "smoked" the exhaust and found that both catalytic converter gaskets to be leaking. So they replaced the gaskets.
Afterward they test drove and found that the car was still running lean, so they "smoked" the intake and found that the intake manifold was leaking. Replaced all the gaskets.
Car appears to run fine now.
