O2 sensors

[Ukwinnie]

Hello Folks from over the pond,
I need to replace the O2 sensors on my 2005 Voyage with 8.1 vortec engine,
Gm sensors part 12572706 does not cross reference with anything I can find,
Some other 8.1 vortecs have numbers 12572705, 1257207.
My question is are any of these interchangeable, as they only adjust fuel ratios,
Is 12572706 a number generated just for Winnebago ?
Can anyone recommend sensors and suppliers, keeping in mind they would have to ship to UK.

Thanks in advance

Regards
John

Gm sensors part 12572706 is NOT a Winnie part #

UKWinnie,
Advise to Try cleaning your o2 sensors with MAF (mass airflow sensor) cleaner before replacing them.

Thank you very much for all your information and help

I am going to try clean them with MAF cleaner and see where we go from there

"Winnie" is a 2005 Voyage with 28000 miles on the clock. Has history of just

passing emissions test the last two years. its got a Propane gas conversion,

which creates a lot of water in the exhaust, I had the Lambda checked on

Petrol and LPG both spot on, so the consensus was that the cats didnt get hot

enough to dry them out, unless I thrash it down the motorway on petrol, and

that negates the saving by running on LPG, I replaced the Cats (from Summit)

they get hot!! so my thoughts were to replace the o2 sensors, but I shall try

cleaning them. Thank you once again for all your help.

Now to stretch our relationship more! "It never rains but it pours" I went to

bring lounge (2 motors) in and no go Handbrake warning light flashing, used

override to get it in. arrived on site and it wont slide out handbrake warning

light flashing, no green light code, had a quick check for loose connections,

pulled plugs on controler and reinserted them , room moved 3 inches then

stopped, would not move at all override to get it in again, rear slide works ok

no brake light flashing on that, which would suggest its not the Handbrake

Any thought my friends?

Regards

John
