I have an 05 supercharged TL, and I was wondering if anyone could help me with the diagram of the cylinders being fired in order, cause my car is putting out a code or PO305 and I have to switch out the spark plug for the 5th cylinder anyone could help??!??

I think the firing order is 1-4-2-5-3-6

 

But i am still searching for an engine cylinder block diagram

 

oh ok let, me know if you could find it cause I have to see which cylinder number 5 is so i could see if i have to replace the spark plug haha
