----------------------------------------------------------------
Hi, I've just recently installed a dual conversion exhaust system on my v6 mustang which includes an x-pipe with high flow cats. I have a DTC PO156 and PO161. I have already had to replace the Oxygen sensor 1 Bank 2, and Oxygen sensor 2 Bank 2. After i drove approximately 11 miles the engine light came on again! I don't know what else to do. What can cause this to happen???

sounds to me like a exhaust leak on that bank or a possible issue with the sensor wires being hooked up backwards....

get back to me.
