Default "Poor Engine Perfomance" message on dashboard

My 1996 XK8 intermittently displays this message on startup. (Poor Engine Performance) with an amber light. The engine alternately surges and fades upon acceleration when driven, but runs perfectly when on Cruise Control.
I have subscribed to two computer analysis tests with no positive results. Can anyone advise on a possible action to redress this issue please. Thank you for your attention, best wishes Dave Jeynes Gold Coast Queensland Australia.

Welcome to the forum David.

If you have an check engine light there will be a code, please check and advise.
A cheap code reader will do the job.
