Post Flashing Check Engine Light

2007 Cadillac CTS
105,000 miles

Does anyone here have the experience of ever having a flashing "Check Engine" light on their Cadillac CTS or other model?

If so, what parts were faulty, or are there certain parts that go faulty with a flashing light? Your help in this matter would greatly be appreciated.

Flashing ses indicates misfire or condition that can cause cat converter to fail. Codes will be set indicating where to look or car should go to repair shop if DIY is not your thing.
