Wife just drove the cruiser back from Oak Island, NC. (300miles)
When I went to check out the cruiser the MIL was on.
Got the code pulled and P04020, catalytic converter bank 1.
Had the code cleared drove it home, no MIL.
Drove to work (10miles) no MIL.
Was suggested that I add some SeaFoam to the gas.
Does the code mean I need a new catalytic convert in the near future or is it a bad 02 sensor?
Any advice is greatly appreciated as I have until Friday to pass inspection
