Check engine light
 

I took my car to auto zone and the code that came up was P0420. Someone help please

Hello Member
 

Your Auto Zone code reader must have been a real dip..report him to his manager for not telling you what was wrong .
P0420: 4 possiable forrays.
#1 Engine could be misfiring
#2 You might have a large vacume leak in your vacume line
#3 Catalytic Converter defective which will also mess up your 02 sensor.
#4 You might have an engine oil leak goining into your exhaust valve guide seats and piston rings.
