Re: O2 sensor help...
You would have to check the signals at the ECM connector, if it's a different reading......time to do some wire tracing. Suggest you do a codes scan to get more information. If the .5-.6 vdc (rich condition for the ECM) are not being read, the system will continue to "add fuel" to the mixture, as you already suspect. LUK
