What do you need to check codes for a 1996 Q45?

The check engine light just came on after I changed the plugs yesterday and someone suggested checking the code(s).

What do I need to do this.

Thanks.

If Im not mistaken 1996 = OBDII hopefully you know what that means, if not well just ask.

Autozone will usually check your codes for no charge. If you have one in your area, try them. If not, you need an OBD II code reader, about $80 or so.

Great to know.

Although I went ahead and pulled everything apart and found that one of the coil connectors had come loose enough to cause the motor to run rough.

Now I know when the Nascar guys mean when they drop a cylinder, no power and it has the acceleration of a farm tractor.
