druhl Posted October 21, 2004 Report Share Posted October 21, 2004 Can anyone tell me where I can find the driving cycle for the 97 seville STS.

druhl Posted October 22, 2004 Author Report Share Posted October 22, 2004 Just to recap my problem. I have a 97 STS and I can not pass the emissions test in the great state of Pa. because I have 3 readiness sensors that are not ready. The sensors are the catalyst and two oxygen sensors are not ready. When I asked about the drive cycle in my earlier post I was refering to GM or Cadillac drive cycle to reset the readiness sensors. But Guru I think you may have something about the O2 sensors having low activity, tell me more. Link to comment Share on other sites More sharing options...
