the computer uses the info from the o2 sensor and calculates the air/fuel ratio and adjustes it as close to 14.7 as possible. If the ratio is off, the things that u said will be affected

IMO, the o2 sensor shoulnt affect idle or hesitation at all Ive replaced heaps of sensors only due to bad fuel consumption. remember the sensor is only a trimming device and yes maintains the best af ratio suited to the engine load. If the 02 packs it doesnt mean it will run extremely rich or lean as everyone thinks. The computer has its own preset modes for when it does play up.

i know you can get gauges that read the air fuel ratio, i was wondering how would you hook this up??
