Well, tonight I changed the TFI module. I took the stock Motorcraft (e6sf-12a297-a1a) module off because it had 106,000 on it (probably shouldn't have)and figured it was about at the end of it's life. I replaced it with a BWD select module.
I drove the car around and it seemed to perform better but I notice now the catalytic convertors have the typical sulfur smell. Is this because the car is now "rich" and not burning all of the fuel? Maybe the BWD module isn't as good?
