Check the code, see whats wrong, fix it

 

people are going to tell you to search my a reconmend reading the cel thread on the top opf this fourm. may come in handy. plus you need to make it throw the code then people would be able to help a little better.

 

Go to Autozone and borrow their OBD scanner to get the code as well as the exact description of the problem.
