Already cleand. Looks like new and silver.
During the search about the IACT I found some site which says it can also be the O2 sensors, because if where coolant in the system the sensors might be damaged. I had coolant in the system before the engine were fixed. I am now trying to find out how many O2 sensors a 1998 Lumina has.
