Re: [doc] couple of tech questions

["blackaddertoo" <blackaddertoo@xxxxxxxxxxx>]

so far i found one mouse nest behind the front grill and one in the 
cubby box behind driver, and some rubbish round the idle ecu.
the wire from the lambda sensor has some chew marks and has exposed 
the shield part of the cable.
maybe i should pull out the lambda ecu to see if the mouse had chips 
for dinner!!!!.
not sure yet how i can replace the shielded wire as its built into 
the connector i think.

Regards

Steve
