2002 Forester, 108,000 miles.
Check engine light first came on after improperly replacing gas cap. Now comes on intermittently even when cap on straight, although currently off. Computer diagnostics indicated catalytic converter ($1100!) Is faulty (tested when light off). Would like to change (or have changed) emissions filters to guarantee these aren't part of the problem. What should be replaced?
