Thanks for the responses guys. JFP, that's a little chunk of info that I haven't heard before. Makes some sense actually. Car always smells rich at startup.

Only one of the O2 sensors was replaced...should I replace the other pre cat one and see what difference that makes? I don't have a durametric but I'll try and get some fuel trim data. Is it possible that all four o2 sensors need replaced?

JFP, regarding the leaking injector, is there an easy way to tell which one would be leaking? the fact that I've got both 1128 and 1130 means it would have to be at least one on each bank right?

Exhaust leaks I don't know. I don't think so, still with the stock exhaust, and I don't hear what would sound like an exhaust leak to me. Thanks again for the info, nice to have some new theories. I really have been chasing my tail here...
