A few months ago, my check engine light started coming on. It comes and and goes off randomly. When it does come on, the car starts to run a little rough, and the speedometer stops working and the AC stops working, just blows warm air out. When the light goes off, everything starts working fine again.

The only way to find out why its behaving like that is to pull the codes from the computer.
