MN 07 TAHOE Z71
TYF Newbie
Recently purchased a 2007 Tahoe Z71, less than 2 hours after leaving the dealership the check engine light came on. Code is P0420, should I jump right into replacing the catalytic converter or is there something else I should be looking at first?
I was told it could be from condensation, a loose gas cap or possibly a bad 02 sensor. I had the light cleared and it came on again about 4 days later.
