o2 sensor help needed (archive)

[ Follow Ups ] [ E30 M3 Message Board ] [ Msg. Board FAQ ]

Posted by Darren I on August 21, 2000 at 16:02:14:

Guys, i have an 88 euro m3 (i'm in uk) the car was fitted with cats from factory, but when the exhaust needed replacing, i fitted an o.e non cat centre section.
my question is: can i disconnect the o2 sensor now that the cats are no longer in place? i'm sure i've read that some owners have got smoother running/better gas mileage by doing this. will it affect the computer/afm adversely.
U.S guys: note that cats are not required in uk for pre 1993 cars.
thanks for any help/ comments.
