Thanks pal.....all just so frustrating....
Primary lambda is in the cat right? exhaust leaks around the cat area maybe? As this is the only area that has been messed around with.
The map sensor was replaced like 10k ago so strange if that is duff...
All just a proper headache!
Was thinking of just getting a new lambda as this was what the original code was....
Grrrrr!

 

Primary lambda is in the manifold, just before the cat.

Any leaks around there, mostly before it, will cause you issues. It may be the wiring down there - which is when you need someone who knows how to use a multimeter / OBD scan tool.

 

Smoke it and scope it

 

Yup. Do you have a smoker?

 

basic tools these days, you gotta have a smoker and with the code's above I'd smoke it first then do the usual clean outs, clear codes and scope the sensors

 

I guess you could improvise at home... i've actually seen something similar with cigarette smoke

We use smoke bombs on big turbine air intakes.

This does feel like an air leak problem.

 

Yeah i've seen the guy with the cigar, you need the pressure though most run at 1 1/2 bar so will show up even the smallest leak,,

 

Really...? Where do you blow smoke...? haha and what with...? Sounds a bit mental...

 

Scrap the car I'm thinking. Its doing my head in...

 

I use a machine, but this guy has different ideas
