Has anyone heard of one of these computers going bad before?

are you talking about the Ignition Module/Control Unit? if so, yes. i have had a few go bad do to wireing problems throu out my truck. i know when mine went bad i had no spark. i hope this helps some

No sorry I am not referring to the ignition(TFI) module. I am asking about the processor located under the dash.

I guess no one has ever heard of the thing going bad then?

Yes they can go bad, but it's not very comonplace.

thank you for the reply
