Oh, also, with the idle problem, I have a little bit of info here that might help diagnose it. When I pop the car into neutral when I'm just coasting along, my wideband o2 will show ~11-11.4. Every 8 or 10 seconds the car will sound like it "burps" and then the wideband shoots back up to ~14.7. It stays there less than a second then goes back to a really rich AFR. When the car "burps" the rpms drop down a few hundred.

Any thoughts? At least its trying to get to a normal idle. This is only after I've been driving the car for a while. On a cold startup it idles perfectly.
