How fast should the O2 sensor react?

I was just looking at Theo's web site.

<a href="http://home.planet.nl/~Jennit/Technical/Technical.htm" target="_blank">http://home.planet.nl/~Jennit/Technical/Technical.htm</a>

Under the O2 sensor it says that the sensor should react with in a a second. If it takes 3-4 seconds to react to a pulled vacume line, then the sensor is too slow.

Is this correct?

Could this cause a wobbaly idle, dieing after a hard, full throtal acceleration followed by a quick stop, and other similer problems?

I know my sensor take more than 4 seconds to react to a major vacume line being pulled.

btw, thank you Brandan, I checked my pressure regulaters, and they are working well. The fuel rail pressure tests OK.

 

Well, if we don't know how fast the sensor should react, anyone know what the Bosch part # is for the universal sensor?

Thanks
