Where can I get some spacers for the sensors ? And finally just to confirm is the uprev an ECU remap ? and how would be the best people to carry it out ? Thanks again for all your help guys

Hi Darren b sounds good. Will the HFCs cause the mil light to come on?

HI everyone thanks for looking at my post, My engine light is doing my head in!! it has been in to a Nissan dealer to have the fault code read and diagnosis but we are not getting anywhere. Has anybody else had this code P0430 TW Catalyst SYS-B2. The first time the light came on the code was P0420 TW Catalyst SYS-B1 (drivers side bank) so the dealer advised replacement of the rear 02 sensor on that side. This was completed and for a while the light was off, however now every time I do any motor-way driving Constant speed around 3000 RPM the light comes back on and the SyS - B2 fault code is displayed. the light does not go out with restarting the engine but is on all the time until I go into the dealer to have it turned off. Can anyone help?? I have a feeling that one of or both the cats are at fault but with new cats at £1500 each dont want to make a very expensive mistake, (the dealer has advised that the cats need to be replaced and then possible further testing) I am also concerned that this fault may be with the engine and may just knacker new cats in a short space of time. Any thoughts or ideas welcome!! Sorry forgot to add the engine is running fine with no hesitation or missfire. Thanks for reading Ed
