What is the code(s)?

If you go to Advance they have a scanner that'll tell you exactly what the car says is wrong. Pretty damn handy.

Tell us the exact codes that the reader pulled so we can help diagnose. The crap they told you is useless.....

i know that didnt really tell me anything at autoszone so i will try advance tomorrow and get the code and let all of you know.
by the way i appreciate the feedback from all of you.
