Hello,

I have a slight running problem with my -96 RS2000. Sometimes it doesn't start well and sometimes the idle is jumping and car is obviously running very, very rich.. for example if I floor the gas Esco hesitates a while and coughs and then starts to pull.

I took the fault codes with my Draper reader and I got fault code 29 which is oxygen sensor 2 (cylinders 2 & 3) failure or mixture too lean/rich.

So it seems that I need new lambda sensor and the question is:
There is two sensors, another for cylinders 1 and 4 and another for cylinders 2 and 3... what's the difference between these two lambdas or are they the same and interchangeable?

I'm looking to order

or

All kinds of information and help is very welcome, since the car and the lambda-thing isn't that familiar to me... shit, miss my ersts2..

MANY THANKS ALREADY!!
