hey guys

Recently i checked my car at bosch repair center computer checking mentioned closed loop blank 1 and 2

i changed the 04 oxygen sensors (new) + i removed the catalyst but it still showing me close loop sensor 1 and 2 , the service advisor told me its cos of the car American specification they r using different petrol octane ,, actually he didn't convinced me at all,,,,, this is first


second i used to have a problem with my z350 2005 manual that the SLIP and VDC lights comes ON and the idl not moving more than 1000 rpm ,, i changed the mass air flow and i cleaned the throttle body and the problem gone for around 2 months now sometimes it happen again but directly when i switch the injection off and again on every thing come back to normal,, this is next my bad


at the computer checking it shows error number p1031 after refer to the manual i didn't get it actually i didn't understand what I have to change so any help on that too


finally i know its too much but am sure some expert around will advice me


regards
