Rlg,

I used to run to Auto Zone when I had a check engine light, or to clear a code..as was stated if it's a complex problem you may need the MB laptop.

I also found that if you buy the handheld computer for about 150 bucks....you will never see the check engine light again!

But, you will be a hero to your friends with a "check engine" light on..
