So guys I need some real good info here. I just started at my new job and funds our tight, I have a fully clogged cat, truck won't Rev past 2500rpm. I removed the upstream 02 sensor and boom brand new truck, so my question is will it be okay to leave the 02 sensor out for two weeks from today til I get the cat? And gutting the cat isn't an option no access to a welding machine.

 

Won't really hurt anything, it'll just run rich and give you lower fuel mileage.

 

Well before the cat clogged it was running rich so shouldn't be a big difference. Thanks

 

Tie it up so you Dont rip it off going down the road

 

Or unplug it, and toss it in the back seat till you can address the cat. Also, I would be making my best effort to figure out WHY it was running rich, otherwise, the new cat will go the same way as the old cat.

 

Well I ran all over yesterday without the 02 sensor in. And man oh man it felt like a new truck day and night difference, it won't be like this for long. I'm taking it to the shop to have a new cat welded on Wednesday. So I appreciate everyone's help.

 

Be a good idea to replace that O2 sensor as well, whatever plugged up the cat. has more than likely been fouling the sensor as well.
