Hi Doug:
When a 911 pings, its damned serious business and the car should NOT be driven until the cause is found and resolved. The consequences are far from being just "annoying". You will not get any warning lights; the ECU does its own thing and cranks back the timing until it ceases.
I would first mix 10 gallons of unleaded race gas (Unocal 100) in the tank and see if that make any difference.
Is the car chipped?
How many miles on the engine?
