I changed my cat covertors because they were leaking and had holes in them... and now my check engine light is on... I suspect its the O2 sensor and had it checked... Code is 25 and its some kind of air/fuel ratio error... but the car runs fine, no rips or hesitiation... so my mechanic says its fine.. but is it ok to leave the car with a bad O2 sensor? any ideas ?

 

its a bad idea to leave it as is, because the fuel may run too lean or too rich...but that is my opinion.


in any event, you see there is a problem with your car. you should get it repaired. leaving problematic situations untouched could lead to more problems on top of more problems costing you more money than the first problem. good luck with whatever you choose

 

yea I know... I'll if I could reprogram the comp or perhaps I guess buy new O2 sensors... if so.. could i get any o2 sensor liek from Kragen or sometin?

 

what do you know.. the problem fixed itself after replacing my EGR pipe.. i guess the bad exhaust flow and leak really jacked up the car.. the light is off and I think its starting to recalibrate itself
