Looking for some help
My 02 sti limited cel light comes on when on the motorway boosting at full throttle overtaking.
When I stopped and re started no light until boosting over a long overtake this time half throttle.
Any ideas?

 

code reader.

 

^^^ as above need a code mate, anything would just be a guess. possibly knock sensor fault or excessive knock going beyond preset parameters in the ecu

 

Thanks gents will get it done today

 

Been to local garages their code checking software can not retreive or even establish connection with the ecu.
So i have ordered from Mocom a tactrix flash cable can any one recomend software to use?
