Hi today my car's check engine light came on and started driving kind of rough and idling kind of rough. The car shut off on me twice while idling at a light and had to restart it. My car is a 2007 Chevy Cobalt. I managed to drive to Auto Zone where they said the codes were P03000 & P0420.
I googled the codes together and saw that some people said this may be a catalytic converter issues along with an o2 sensor. However on top of the Auto Zone print out it says that its most likely a fuel pump that needs to be replaced. Any idea based off your experience what this might be?
Trying to get an idea of how much I'm gonna have to spend.
Thanks in Advance for the HELP!
