How long can I ride with a bad o2 sensor before it completely screws something up?

 

what yr and model? how many 02 sensors do u have? do u have the converters on the car? any mods?

 

Won't screw up anything major, just run like crap and potential is there to foul plugs of course. The pcm will just dump a bunch of fuel in and the car will run rich. You have 3? 2 front one rear, non-heated? At any rate, should be ok for a while but might drop a cylinder as you foul plugs and im assuming you only have a few to spare.

 

97 RS 3.8 V6. But yeah I'm probably just going to leave it parked until I get one because i'm broke as a joke atm and don't want to have anything else in the way of me saving money for upgrades.

 

bummer pretty sure the 97 has four 02 sensors. have it scanned and see if u can get more info. may save some of that hard to get bucks.

 

Ever thought of an O2 simulator instead? If it's just for the one(s) after the cat, it's only emissions related...
