When you've got your engine idling normally (~700-800), turn on a heavy electrical load (ie. rear defrost, blower motor). Do the RPMs drop, or rise?
If they drop, it's probably a stuck IAC. It's not closing the intake during cold starting, and because cold air is more dense, it could be running too lean to light up, then too rich on the next stroke.
If the RPM rises, your IAC is working properly so it's something else. In my case I know I had all sorts of vacuum leaks at the time, and a gunked up VAF. Bad compression or bad disty I'd suspect first.. :/
When you push it into the garage, do you pull the plugs to let it air out, or just let it warm up?
I'd strongly recommend ordering a USB OBD-II reader off ebay. They're like $20-30 shipped, and make life so much easier. You can read the codes, as well as monitor things like intake air temp and coolant temp. A bad coolant temp sensor can also cause trouble (because it's the ECUs primary engine temp source), and something like that would show up in the sensor log.
