So, I get a quote from my "local" Porsche service to replace my EEC because it is completely clogged and causing that bright orange disc on the dash to shine.  All they want is a measly $1100 to do it. I have generally just re-set the code. What are my options?  Can the EEC be disconnected, re-routed, cleaned or what?  What damage am I doing at this point?  The beast is a 1998 and has 91K on it.
I meant "Emission"
