How Safe Is It To Run With Your 02 Sensor Out?

[davematthews-S4]

Mine has been out for 3 weeks :whistles:

[SKperformance]

which one

you have 3 sensors

2 before and one after the cat

it isn't unsafe

just you might over work the cat by running rich and causing the car to have more power

i doubt the exess gas might cause the cat to overheat

but your gas mileage should go down
