Lambda problem

[simonman]

i changed the plugs about a month ago, changed the lambda last week, changed the fuel filter last week. i dont think it will be the leads as it sometimes drives fine.  i have bridged the cat heat sensor.  i am thinking of trying the water temp sensor as someone mentioned it could be that.  what do you think i should try?
