Hey sorry for the late reply man been mad busy recentley i got the lambdas from alan quine ltd its a small shop in bury
Alan Quine Ltd
253-255
Parr Lane
Unsworth
Bury
Tel - 0161 796 5797
the spanner is 22mm i bought a 22mm spanner and the 2x lambda sensors it cost me £106.89 all in inc vat there ntk lambdas too so there good quality and direct fit no cutting wires etc like the cheap ones you get
Trust me though man get a fault code reader like this
http://cgi.ebay.co.uk/UNIVERSAL-HAND...item45ee2ac075
ive got this and it works on most cars and its easy to use saves you paying £50+ to have them read at a stealers
when you have your codes eather read the book that comes with it or goto
http://www.obd-codes.com/
and type the code into the search for a better description of the fault its well worth knowing thats the fault for sure these codes i had i read off my own car so i new exactly where to start getting to work these are one of the main faults on st170's tbh but it does drive 100% better when its spot on i get around 50 to 55 miles to 10 litres of fuel now (about £10.70 ish i fill up by the ltr not the price as it changes so much from town to town) thats day to day driveing with traffic starting stoping etc dont get me wrong if i boot it some i get less but thats good really it was unreal how much it used with the imrc fault and both lambdas not working ive drove 2.8 and 3.2 petrol cars that used less fuel when it wasnt running right its pritty much doubled the miles i get bearing in mind my car is standard engine wise no mods like induction kit de cat etc
hope this helps
cheers mark
