1) rattle at 2500rpm is usually the heat shield, it's not easy to see. crawl under the car and tap the exhaust, you'll see/hear it.
2) your O2 may be going bad.
have you done a tune up?
(new air filter, fuel filter, cap/rotor, plug wires, plugs)
"I tried some of those fuel injectors" - what? do you mean fuel injector cleaner?
or you replaced the fuel injectors?
