Second failed catalytic converter Bank 1 on 2004 Yukon
Has anyone else experienced failed cats on bank 1? The original stock cats failed a while back, with a broken piece rattling around. The second set was a cheap brand from Rockauto and again bank 1 failed by plugging solid. Any thoughts or suggestions of what the causes might be will be appreciated.- PNWYukon
