But I don't have a lot of money and
I've been told that there is like a

Autozone or Advance auto will scan your car for free. Post the 4 digit codes back here for more help.


I would just suck it up and take it to the dealer. By the time you purchase a decent code reader (like BavTech's cable and software - $200), you will have paid for the dealer visit. Also, if you are popping a code for a burnt out light, that is an easy swap out ($6 for a new bulb).
