My Impreza 93 wrx wagon is running rich, have been told by subaru garage and there diag machine it is the lambda sensor at fault, can someone please advise me on a part number for this sensor (bosch etc) and where is the best place to get one (cheap too!), it does not need to be a new one but i need to get one and i refuse to pay the stealers £200 for one!, it is the one that fits in the exhaust towards the front of the engine (not downpipe) and has a little connector plug with 1 white wire, 1 red wire , and 1 black wire. Any help very much appreciated thankyou.
