Help with my 04 galant
 

I have a 04 galant gts that lately has been idling a little funny. My tcl light comes on randomly and my service engine soon light is on. I just got a steering flush, air filter and oil change if it makes a difference. I went to autozone to read the code and it said my fuel was too rich. Anybody have an idea what's going on? Help would be appreciated!

What was the exact code? You may need to clean the throttle body and/or IAC.
