Hey guys I have an 04 si and today my cel came on...I went to autozone to have it checked and they told me that my primary o2 sensor has no response...just wondering how big of an issue it would be to drive it this way for a few weeks while I save up for a new one...and info/opinions would be appreciated.....

 

not a big deal. around 200 to replace, use the search button next time....amazing things happen

 

Worse thing that could happen is it would cause you to run lean.

 

It should be running rich not lean. If the ECU registers no O2 it will go into limp mode which puts it in open loop and it uses more fuel to protect the engine.

 

thanks guys i will replacing it as soon as i get the funds
