Does it sound unusually labored when driving? Cat may have failed and be clogged up.

Took it to advance auto parts and they did a diagnostics test and it showed codes for an oxygen sensor and the canister purge solenoid. The canister solenoid has something to do with the emissions.

Which sensor. Bank 1 or 2?. Better yet what codes popped up?

If it's saying your 2nd o2 isn't working I guarantee it's the cat.

The purge solenoid could be doing it too.

Bingo.

It was bank 1 sensor 1. Said it would only effect gas mileage

OK it the first sensor. And NOooooooo it affects the whole car. That sensor is what regulates many things as in how much fuel to let injectors dump or how much air to suck in by controlling throttle body. Its a very special sensor. If your boosted forget it. It can cause havoc. Did you get the specific code? Could be electrical.

Buy some throttle body cleaner and thoroughly clean the inside of your throttle. It should idle slightly high for a couple days afterwards but once the computer has a chance to compensate it'll will come back down. It's a fairly common problem. Also, like stated before, make sure it has enough oil.
