7miles, Thank you for the info but after doing some "homework" on the internet I'm wondering if I'm now running CEL code P013C. I haven't had the code rescanned yet (after I installed the spacer last week) but it's possible right? If so, I guess it's back to trial and error but like I mentioned above to Eggman, I don't want to purchase a new converter just to keep the car for 8 more months.

The spacer in the pic below is shorter than the one I currently have installed on my car atm.
