Just wanted to share a tip that you can look up service engine codes on the Internet so you know what kind of issue you're dealing with. Some cars allow you to see the number on the dash while other cars you have to take to places like an auto parts store.
Never thought of looking something up on the internet. I hope my car doesn't show a code for a long time though. Would have helped with the last car though. I couldn't get my check engine light off.
I discovered the use of the Internet in an act of desperation. I had the code and thought, "what the heck!" and there it was with an explanation of what was causing the problem.
I always take my car to Auto Zone when the light comes on because they will put it on the diagnostic tester and tell me what the code means. I have never needed to look it up at all.
