Nothing. I have found numerous post on forums and blogs. People have tried everything thing including putting ferriets on every wire under the valve covers and on the outside of the motor. There is no fix!!
Btw....a snifer test has been done and the problem comes from the wires coming out of the computer going to the injectors. They have wrapped the wires in tinfoil and all. You name it, it has been tried. Its not the computer that causes all of this. Its the injectors. Different injectors draw different current. Change the injectors and this problem will be solved.
