Swapping lambdas.?

[welsh.Z.S.]

Hi my lambda sensor (before cat) is playing up, making it run like crap, would swapping the sensor with the 1 after the cat sort it? Any downside to this as I heard the sensor after the cat doesn't effect the running of the car? It's a ph2 172 btw

If its definitely the lambda then yes - that should work.
