Having problems with your 1998 Ford Mustang ?

I had my O-2 sensor replaced about 2 yrs. ago on my 1998 Ford Mustang GT, 4.6 liter several years ago. My check engine light came on a month ago and the Dealer told me it was the O-2 sensor. Do I have more than one and shouldn't the Dealer replace it free of charge? Also will it hurt my car if I ignore the check engine light and drive it, they told me it would cost $500 and that I should get it fixed. Teri in TX

Answers :


$500 is a bit high. The sensors are on the exhaust and basically they help your car exhale. If you continue driving on a bad one it will throw your exhaust, intake and finally engine off key...

They cost about $90 buck a piece if you dont shop around and you can ask a tech savvy neighbor to put them in for you. The website below should be of help.


Good driving.
