Ok, after a new CTS, ignition module, and complete R&R of the all plugs, the car is running. Its idle is rough, like the cylinders aren't firing evenly. It will go through the RPM range, but hesitates/burbles on the way up from 1K to 3K or so. Puffing a bit of white (moisture) and huffs out a nice bit of black when you get the RPM's up. Any ideas? O2 sensor shot? has a new MAP on it.

Also, my fans (both of them) and my HVAC stuff has quit working. No fuses blown for the AC in the fuse block....Is there something else I can check?
