I dont know if my DISA valve is wide open. I thought initially that by just replacing it altogether, the CEL would go away. So its new, just that no second wire to it :/. How do you make it wide open?! |
You have the 668 DME on a 1997. DISA is closed blocking a set of 4 intake runners from idle to around 3,500rpm. Opening around 3,500rpm allowing all 8 intake runners to supply air to the intake valves. I idea behind this is it supplies the motor with two manifolds one set of runners then both sets of runners in higher RPM. I just take a old DISA valve and break off the rod and flap and any loose metal then plug the small holes on the outside with JB weld and install it in the manifold, car ran great like that.

You should have two wires running to the DISA red/white(Branch to 12volt for most sensors on that page) & brown/blue(Pin 58 DME activate DISA)
