I have a 2001 Honda Civic. Not much more than a week ago it was replaced. It was replaced with a used ECU, but still, what are the odds that another one blows in that short of a time period?

Any ideas what could be causing this?

 

Bad grounds kill the newer ECUs. On the K-series it's a ground on the valvecover, not entirely sure on the base models.

 

Mine is a 2001 Civic EX Coupe.
