[QUOTE="1wild-horse, post: 16381671, member: 84197"] You can use a simple vacuum gauge to test for exhaust restrictions. Hook it to an intake vacuum port and power brake. If the needle falls to zero you have a plugged cat. From there, you can remove an upstream O2 sensor , one bank at a time and give it a quick drive to narrow down which one is plugged. [/QUOTE]
