Possible to Swap Lambda Sensors??

[caister]

I've noticed a a steady decrease in fuel economy so I'm expecting the lambda sensor. Last time I checked both sensors, the pre-cat one was quite carbed up and the after cat looked almost new. So ive got a few questions:

1)Should I just buy a new sensor and be done with it?!
2)Is it ok to swap the pre and post cat sensors around and should this solve the problem?
3)Is it possible to clean the sensor?

Cheers

you will need to chop the loom if your swopping post cat to pre cat as loom is to short, lambdas are both same, thats of course if you think its the lambda causing your problem.

Both sensors should be the same, just one has a longer lead, so as long as the lead reaches mate then there shouldnt be a prob

Cheers guys. Not sure it is the lambda as I got 39mpg on the way home tonight!

I've got a feeling it may be an adverse affect of driving in Germany last week and my foot still being a little heavy on the Motorway!!
