O.K. I've been battling this running fat form my 02 WS6. Now occasionally I get a flashing ses light but no code to refer to. The car is still rich as hell and I've read all threads relating to this , but everyone else had a p 301,302,303etc telling what cylinder was the culprit. Please help!

You have an aftermarket tune? The codes might be turned off or marked no fault found but the light may still come on. Just a thought. Check what your ECT is reading. If it is cold it could be a false rich condition. What are your fuel trims at? That could tell you if it is a true rich or a false lean condition. Both will make it actually rich in the end. g
