Ive just replaced mine on an MY98 STi and the symptons were uneven idle, very juddery when driving with light throttle and also **** fuel economy. On a plus side it used to pop and bang on over-run.

Im running an 3" de-cat system and is running spot on now!!!!

same as me m8, jerks when driving slowly in traffic, and slight miss every now and then on idle, are they easy to replace? are they very expensive?

Overfueling is the most common symptom. Very easy to replace.

Very easy to change, mine is located just after the turbo (Downpipe) and there should be a white plug where the lambda connects to the wiring loom. Think you need an 21mm spanner to unscrew the sensor from the pipe... Make sure its un-plug first
