Hi Guys,
I'm new to this forum and I need some expert advice. A friend of mine was kind enough to lend me his EZ Scan 6000 so I can check the reason behind this light. It detected a "P0420 Catalyst System Efficiency Below Threshold (Bank 1)". I did change the entire catalytic converter about 2 to 3 years ago and now this. This car is due for smog in June & I have a feeling it will fail unless I can find a fix.....I need all the help I can get at this point. Thanks in advance!
