Why the hell does my car idle?

I do have the pipe from the presilencer to the aux ports (yay RB presilencer). I have 0 emissions stuff. No ACV, BAC (unfortunately), EGR, etc.

I might be running richer. Apparently my car now pops flames when I redline and let off (hehehehehehehe) which it didn't do before. If my aux ports weren't opening but the engine was putting in fuel assuming they were (does the ecu work that way?), then I could see that.

All that said, still not sure why my idle is good now. I would think a vac leak would cause my previous symptoms, not my current "symptom" of a good idle.

I just find it all odd that the only change I've made is the exhaust and this happened right as I did that. Seems a bit too conincidental.

A wideband would help... know anyone with one that I can borrow?

I can bring it over or you can stop in, either works. We'll figure it out. As a side note, I've been driving it to work which is kind of a nice change. Now I just need A/C..............................................GAH !
