symptoms of bad 02 sensor?
arent symptoms poor mileage,rough start, idle and run under load? advance is selling a cheapo 35$ oxy sensor and my father, nor me, has never replaced the stock one in 165K and 10 years of miles so i believe its in disrepair. and will change rear differential fluid save gas by giving boost to mpg, buddy says it wont but i know it will at least a little, also this has never been replaced by father.

Those are symptoms of a bad o2 sensor on an OBDI vehicle, on an OBDII vehicle, symptoms of a bad o2 sensor would be heater circuit codes, rich codes or lean codes. a rich code will cause the vehicle to run lean, and a lean code will cause the vehicle to run rich. o2 sensors dont commit suicide (except the heater circuit) there is usually something else that causes them to go bad...but replacement 100k intervals are recommended

my check light isnt on but truck runs super rough idle and often stalls when i roll out of the drive way. and the exhaut (from what i smell) smells like very very little gas IS making its way out, so idk, advance is having a sale on 02 sensors so just wanted opinions. this has always been a problem with my truck so just thought id bring it up

yea, i dont have the money for a diagnostic thing, and a fellow car junkie around me sold his tool on craigslist, so ill just live with it, it seems as if the fuel pump is going funky but when i really get on the taps she roars but at really low rpms (<1000) or just over she sometimes stalls and does funny things so ill just live THANK YOU GUYS
