Quick question what is the lamba sensor thread size.

Put a spanner on the lambda and hammer the crap out of it, worked on a good few stuck sensors for me.

If i can get it out am i best to fit it to de cat or just cable tie it up behind heatshield?

I'd bung the hole and tie the sensor up, pretty sure I've got a couple lambda hole bungs in my tool box. Easy to get and pretty standard size across most cars

Blow torch. I used one from b&q, heat outside of where the thread area would be till it's almost literally red hot and then spin that b**ch off.

Pain in the tits but worked for me. The torch has paid for itself tenfold since, being used no end of times on other ceased stuff!

Id probably just get a proper bung and then bag up and cable tie behind heat shield as you've said.
