Thank you both for your comments.

Regretfully my 2003 2.7 boxster's intermittent P2096 error remains unresolved, still re-occurring every 200-250 miles

With the all the work and tests done to date, the upside is the knowledge that my car has a squeaky clean bill of good engine health.... no "real" lean running at all.But I am not happy with this, and am determined to get it resolved, so my quest continues.

My latest forums research has thrown up this potential fix:

"DME Software Anomaly (2003-2004 Models): If you are driving an early 986 model year (2003–2004), a known software bug in the engine computer (DME) can falsely trigger the P2096 code. If the sensor tests normal, a trip to a specialist to update the DME fuel maps may be necessary."

Hence this post and my question please, has anyone on this forum has the DME update done on their 2.7 Boxster by their Porsche dealer or any other specialist, and did it resolve their issue?

TIA, Rob
