Default Engine Control Unit(ECU)

Does anyone know how you can tell if your ECU has gone bad? Isn't located behind the radio? If this is the problem, how much does a new one cost? Thanks alot... :cheers:

Its located directly up from the pass footwell, behind the breadbox. You have to remove the black hush panel above your feet and its sitting directly up on end.

You would need to list your reasoning behind why you think the ECM is bad to really justify replacing it. There are no codes indicating anything wrong?
