just how sensitive are o2 sensors...seem to have lots fail

[steveo3002]

ive had what seems to be quiet a few o2 sensors die on my golf over the years.i always get bosch ones and handle them with care

just swapped the exhaust over which onvolved remove/refit the o2 sensor and it seems its gone again

are they really that fragile or is there another problem

[steveo3002]

well the car is bucking badly at low speed around town , occaisional buck on cruise

unplugging the o2 fixes it

nah dont have any fancy gear im affraid

in the past new ones do seem to cure it , but i seem to be getting through alot of em

the car is a bit primative really..doesnt have any self dianostics or nowt

havent used any silicone anywhere on the engine , no fuel additives either

[steveo3002]

6 years and its gone again lol

found this old thread googling about them ...i guess 6 years isnt too bad , had a bad misfire earlier in the year so i guess that killed it
