my check engine light came on the other day and i had it checked out today. they said it was the oxygen sensors, and that they had gone bad. does anybody know how much this will cost to fix??

 

my car just stated idling rough. is the O2 sensor the problem?? does anybody have any experience, advice on my situation

 

If it just started idling rough all at once, is there a chance that you have a bad tank of fuel? Happend to me once...it was REALLY bad fuel. Had to replace my fuel filter after about 6000 miles because of it too. Talk about being TICKED OFF, I went back to the place where I got my gas and, believe it or not, got credit back for the gas, they paid for the part, and paid for my troubles. All in all, I ended up with a check for $100. I won't buy gas there EVER again however, I will say, they admitted their fault and took care of the customer.
