Well, my head-to-header connection started leaking bad enough yesterday to make me throw a code, P1131: Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1. With my long-tube headers, it's going to be a real pleasure trying to fix. 
My question is, am I going to hurt anything by running her anyways, especially at the track? I'd assume that reading lean makes the computer richen up the air/fuel mixture. My limited experience dealing with this stuff makes me think it'll do no harm other than waste a little gas and power.
