I have not gotten my new sensors yet (slow). I put the Densos back in and swapped sides as was mentioned earlier. Gonna run it about 40 miles tomorrow and see what happens. I will report on it.

When I was looking up these sensors, I found the 2133866 numbered ones for $35 each, and the 12583804 numbered ones for $53 each. That's why I was asking if there was a difference between the two.

Only the price! LOL

We know they are Densos but the non-GM Densos are different and may not play nice with the computer system.
