Kegger Posted February 5, 2007 Posted February 5, 2007 Can I run my car without running a 4 wire o2 sensor. Its a Z6 with a P28 in an CRX si. Just wondering if I can without too many detrimental effects like crapty gas mileage.
TS John Posted February 6, 2007 Posted February 6, 2007 I think all you'll get is a check engine light. I can't imagine it would do much to performance, but maybe they sense your oxygen levels and feed that into the ECU for fuel/air mapping purposes? Someone please enlighten me.
