2006 Cadillac CTS 2.8L? Or tell me which cylinder is number 3? I have a misfire in cylinder 3. I just need the diagram to show me what one is #3. Also can I get the firing orders for the other engine?

Firing order is 1-2-3-4-5-6. Whichever side of the block is more forward than that should be #1 and 3 is right behind it. So if your right head sticks further forward than the left the right side would be #1 then 3 then 5 etc.

Left side is #1 then #3 then #5, 2-4-6 on right

Determine if it is coming from the differential, or a rear wheel bearing. In the past, the diff has only been serviced by replacement, I am not certain if that has changed.
