a/f as Cody said, you'd be surprised how much it can mess with the fuelling if it's fukt. i had a brand new bosch mess me around and then problem solved when I put the old AC Delco one back in. NTK or Delco form now on

Re: What is oxygen sensor for?

i don't know why either to be honest. 97 2.4. could be a canadian thing as there doesn't evn seem to be a wire/connector for it. and i replaced the motor myself so I would have noticed!
