Was just driving home and my lamba sensor has managed to rip its way out of my pre-cat .
It has completely shredded the thread and there is no way it can go back in and stay there.I placed it back in its hole and continued my journey.
It came out again shortly before I got home but I didnt bother to stop,my car sounded like a tractor but yet through all of this I had no dash (fault)lights appear even after around 3 miles.
Is this just luck or is it possible to block off the hole with a bolt until I have the time to get a new sensor???
