Engine management light comes on when i start driving the car.

I have an issue with my engine management light,
i have replaced the spark plugs and coil packs
also took out the idle control valve and gave it a
thorough clean with brake cleaner, which sorted
the problem of the car switching off after it started
up, but engine light is still on i disconnected the
battery for 24 hours and re connected it to reset
the ECU code for the management light but didn't
work, the light comes on every time i start driving
the car not when the car is switched on, do you
know what the issue can be here?

Ps. I have a feeling it might be the lambda sensors
but not sure.
