How do you diagnose a problem with your '96 Chrysler Sebring LX yourself?

Vehicles that are around 96's and up have an OBD-II computer link up. This palm held pluggin unit costs around $125 - $150 ish online or at the autopart stores a bit more.

The beauty of it is it will diagnose your check engine light problems and tell you what it is so you know what to have replaced. It also resets the light and clears the codes.

I purchased one and it has been invaluable as it works on any vehicle 96 and up. From Chevy to Ford to Porsche to Rolls Royce.
