On the cobalt site. Does it work well on our DI motors.

Do you think Powell will actually come out with something better I know the 3M or wynns method seems to work well on non DI cars.

 

The dealer can also remedy this. Had a thorough cleaning two months ago. And issues related to it fall on their shoulders.
