I've been having loads of trouble trying to eliminate a series of pesky MIL codes on my own. Thanks to your assistance, it is gone!

Turns out that I had a bad set of upstream O2 sensors and one bad downstream sensor (fixed by making my own MIL eliminator). I probably fouled up the upstreams when I cleaned out the UIM and LIM. I never saw so much gunk in an intake in my life.

I also replaced the TSS as per the bang-shift threads and it shifts smooth as hell now and keeps accelerating through high RPMS. Before the part change the car would rev up really easy to the redline, but it wouldn't gain at that much speed.

Thanks for your contributions.
