So pretty much ever sence I did a 3l swap I have always had a CEL on, mind you i did the sway like 3 years ago. I jsut never really cared to much about it because the codes were mainly for the downstream o2's not being hooked up. Well it was inspection time today and sence NYS is so lovely they hook you up to a computer now to check for codes etc. So I kinda had no choice but to take car of everything.
Read the codes to see what was actually wrong and 5 codes came up, 4 for the downstream sensors as expected and one for no switching on an upstream. So I order up an o2 and install it ripping my arms and fingers apart and to my suprize the code is still there. Then I start to think about it it was the bank 2 sensor and for some odd reason I thought that bank two was the rear. so long story short I changed the wrong sensor and proceeded to swap the front one, install some eliminaters and walla no more codes.
I'm going out for a cruize tonight to see if I can feel any difference in the power now sence there is no light and a working upsream in there now.
It just seems strang now seeing the CEL on anymore haha.
