Obama was here for his first presidential press conference. At that time our unemployment rate was 15.3% The latest I've heard is 18%. So 20% was a bit of a stretch.
Warm air intakes; from what I've heard, the Saturns are about the only cars out there that consistently respond favorably to a warm air intake mod. My guess is that Saturns use a manifold air pressure sensor where most other cars use a mass airflow sensor. The MAF based system is a little more sophisticated, and is not 'fooled' by the less dense warm air. It just compensates the fuel injector pulse width and keeps on truckin'. But I haven't researched this out to determine if I'm on the right track or not (as far as Saturns having MAP systems).
