guys

 

before i spend on some new o2 sensors i just need to confirm my findings :mac1:

 

when starting engine from cold the o2 sensors dont range just stay the same both sides,

 

when driving from cold engine is quite hesitant also

 

but when the engine is warm the o2 sensors range up and down just fine and the hesitation has gone,

 

am i correct in thinking the heating element has gone in them? :confused:

 

cheers

if you rev when cold they should move a bit..don`t think they have a heating element,,isn`t that glow plugs? All they do is help adjust mixture

Dont event think they are suppose to work when engine is cold for first few mins.

Anyway they wont affect running really.
