1994 Vauxhall Astra

Engine Performance problem
1994 Vauxhall Astra 4 cyl Front Wheel Drive Manual 78000 miles

The engine management light keeps coming on when the vehicle is stationary. I have to turn the engine off and restart the vehicle for the light to go off. I have had a guy do a computer diagnosis and he was unable to find the fault. He stated that he would have to diagnose individual components as he was unable to get a correct reading direct from the brain. Any ideas?/

He needs to have the diagnostic machine pugged in and monitoring the sensors etc. Whilst the light is coming on at idle !
