Engine Oil And Service Check Light? Please Help

[bosco]

Hi again,

I previously put a post on regarding engine check light on. My v v t i controller is causing the light to come on after I added octane booster. I have used the petrol and used fresh petrol but light is still on. I disconected the Battery overnight to reset the ecu.

Would I go for a change of oil and filter?

Would that make a difference?

Is a days labour involved in the repair?

Is there a manual for a 2001 yaris T sport?

Whilst I will have to do it, is there anything I could to modified the engine with the head off, ie cams etc.

Am I better off with a new stock engine?

Could I go for a modified engine?

I am lost here. Can anyone help me on this forum?

Thankyou.
