i have an 03 cobra and cant get catalyst monitor to run. 1st step i took was took of the bassani xpipe with cats and swapped them for the stock h pipe well no luck still. going to try to swap rear 02 sensors for new ones. Now all the monitors are on in the tune and the car has an egr delete kit so i know that monitor wont set but does anyone have any ideas how to set the cat monitor so it will show ready. please help. drove over 200 miles and never got any codes or check engine light.
