Try socket six, it might cover (test) the knock sensor and the throttle switch.

The knock sensor could have become disconnected or gone bad.

The ignition timing should be dead on since it uses a CPS but the computer may not be getting proper information to adjust for the Ping of lower octane or the load ratio. The load ratio is part of the throttle position duty IF you have the variable type switch that is in the LH 3.1 for 93's.

The resistance type switches can wear in a "dead spot" as they get older.

I do not own a 3.1 but they are good old problem child's on Chrysler products. Anybody with the mid 80's cars know about their shenanigans they left us with in the ICU connector.

This Ping thing has not been batted around much on the BB. This will be a good post to hear what others have to say!
