MK1 ST170 O2 sensor replacement

[blinkydamo]

Hi all,

Wondering if someone could tell me if I have to remove the heat shield over the manifold to replace the front O2 sensor. I have a P0133 error and need it fixing tomorrow morning.

Is it a 10 minute job or an hour long?

Cheers for any help and advice,

Blinky

shouldn't need to you can get to it with a bit of a stretch from the engine bay ideally if its on a ramp you'll get to it easily

Cheers, came off really easily to be fair, jacked up and found on the top of the cat, manual states its behind the heat shield.
