Thought I would post up a final report, I have solved the problem. I did several things, all probably had some impact. These were done over a week or so, gradually the smell went away. I was more interested in fixing the problem than trying to determine the exact cause so I did several things over a short time based on inputs i got here.
1- replaced rear hatch seal, i still have a slight hatch fitup issue.
2- installed a generic aftermarket catalytic converter.
3- replaced O2 sensor, had to install a new bung.
4- set FQS to position 2 to lean it out a bit
5- started running 87 octane instead of 93 ( previous owner said he used 93, i didnt know any better)
6- performed throttle body refurbed, cleaned and installed the Arnworx TB kit
7- Installed closed cell acoustic eggcrate foam that I had laying around in the wheel wells and around the rear behind the carpet in the hatch area. (really helped with road noise)
I seem to have completety fixed the problem, not a hint of exhaust odor in the car. I think 2, 3 and 5 had the most impact. i am going to run for a couple more days with the FQS set to 2 then go back to 0 to see if there is any change.
Maybe this will help another Porsche newbie like myself. thanks to the guys in the forum who kindly offered their experience.
