I'm a new Caddy owner and new to this board. The info is awesome. I knew nothing before, but in just over an hour, I feel like I really know my vehicle now. Just bought a 1986 Deville/Fleetwood Edition that is super clean with 89,000 original miles. The car is beautiful. I've had to replace a bulging rear ball joint on the passenger side. However my biggest concern is the flickering check engine light when my car idles at a stop light. This is the only time it comes on. Any suggestions?

Pull the DTC's (Diagnostic Trouble Codes). Check the sticky at the top of the page.
