As Richard pointed out in an earlier post on 8/11, you can see that YR and YB (the two wires in question to the wheel speed sensor) via the chassis/engine connector are routing via a joint bomb to many of the sensors on the engine. The idling problem is solved when I disconnect these YR/YB wires at the speed sensor.
This could point to the problem being in the wiring from the speed sensor to the joint bomb. Perhaps the solution is to cut YR and YB and remake the wiring from the speed sensor plug to the bomb? RIchardV6 does this sound sensible?
