Thanks again for the reply. I will wait and see what codes are present the next time the CEL comes on. I also learned that my software will allow me to monitor the O2 voltage, so if it sets the same codes I will check the voltage output of the Bank one O2 sensor. I haven't had time to check yet, but would bank one mean pass or drivers side?
Also is it normal for the codes to take so long to set a CEL light? I am use to codes resetting in 30 miles or less. But with this car is seems to take 150 to 200 miles to set.
Thanks again for all your help. I can't tell you how much I appreciate it. Any advice on changing the 02 sensors? I have never removed one and they seem to be the stock units. I was going to soak them down with PB Blaster for a couple days before I attempt removing them. This is if the codes reset themselves.
Have a great weekend.
