Service Engine Light
I own a 99 z28 with 74k miles and my service engine light came on yesterday. I went to auto zone and had them read the code and they said I had 2 codes saying I was rich on cylinders 1&2. The car seems to run fine little rough idle and when I floor it I get a Lil cloud of black smoke. What I need to know is what should my first course of action be ??? what would you start checking first ?

OK, sounds like P0172 and P0175. Read through www.gearchatter.com/viewtopic8885.php Pay particular attention to the diagnostic for throwing both codes. It's pretty detailed and assumes you have a scan tool but you might find something. Hope it's something easy....

Just a little clarification.
