Urgent question

[Acoris]

Hi,
We were changing the exhaust and we damaged the front pipe. We ordered the pipe but forget to order after cat o2 sensor. We heard its nearly impossible to remove 20 year old o2 sensor. Will car work without o2 sensor with the new pipe?

You'll have an engine light on and a serious exhaust leak unless you bung up the hole.

The after Cat O2 sensor if missing will put an EML light on but "shouldn't" affect running, the before cat O2 sensor does affect running if missing.

If the old pipe is junk now there's a chance you could grind it out of there

Just cut it out roughly with an angle grinder and then once you have the old sensor surrounded by jagged metal just go at it slowly with a grinding bit trying not to touch the thread until there's not much holding it in there and unscrew it

Probably just easier to try to get a replacement one though

Its a great idea. We will try. Thanks.
