my03sc430

HI I also have them on my '03 for 18 months now. I get the usual momentary flat spots if the car sits for more than a day, but other than that I like them

Hello and Happy New Year to everyone! Has anyone ever replaced the driver-side downstream O2 sensor? I found the O2 sensor on the exhaust on my '03 SC430 but once the wire goes into the cabin, I just can't seem to locate the connector under the radio area. I removed the shifter plate but do you need to remove the radio, carpeting etc? If so, how does one do this? Thank you for your help.
