Hello,
Is it difficult to replace the 02 sensors in a Vibe?
I recently had the exhaust manifold and catalytic converter replaced in my '07 Vibe (FWD) and I am still getting a P0420 code.
The mechanic said not to bother changing it on an old car (he has an '05 Vibe) as the car is still very driveable.
Would it harm the car if I don't change the 02 sensor?
If I do change it, is this something that can easily be done by someone who isn't mechanically inclined?
Thanks!!
