September 09, 2002 Front Injector Harness On Touring Models. It can also happen to the rear injector wiring harness too. You may encounter an intermittent hesitation and historic front injector code, P0261, on Touring models. If so, the condition could be caused by broken wires in the ignition harness very close to the injector. Since the insulation is not damaged the break cannot be seen. Wiggle the harness to determine if the condition exists. If you do find a broken wire, it is likely due to a mis-positioned tie wrap causing the wires to the front injector to be pulled tight. The combination of insufficient slack and engine movement can cause wire flex leading to the breakage. When you repair the wire, be certain to allow slack in the ignition harness to prevent a recurrence. You can move the harness around by the injector plug and see if the engine stumbles when you do this. It will give you an indication of the problem if this is where you have a break in the wire.
