Just got my S40 T4 a week now and the other evening during hard acceleration the "Fault in Electronic System" light flashed very briefly.Is this somethig i need to look into or was it a normal occurance.

Alot of times under hard acceleration if the check engine light flashes it means the car is missfiring.Could be bad plugs or bad coils.

This light is on my car also. always comes on when im low on fuel and i gun it.
Does it need to be fixed? whats the worst that can happen?

i sense that this light is making my fuel deplete much faster than it usually would. can anyone tell me if im on the right track?

$600.. thats a lot of money to replace it

(model is a 97 s40)
