This technical bulletin relates to ignition knock, surging, misfiring and other driveabiliy problems on the above vehicles, often attributed to other causes, that are caused by the factory wire routing. The solution, recommended by the manufacturer, is to re-route or re-loom the wires as detailed to minimize cross-firing and inductive effects. This sort of problem will be less prevalent on Magnecor than factory wires, but it is prudent to follow this procedure.
Copies of the factory Technical Service Bulletin, which outlines the problem and the recommended repair procedure, are available at:
