Exclamation 5.4 engine cylinder numbers

Hi, all! I'm having a cylinder that is missing steadily, even at idle. My code reader says it's #6 so I replaced the COP with a new one, but the problem is still there. Then it occurred to me that perhaps the cylinder numbers might not be conventional on the Triton engine. Most engines I've worked on the #1 is at the front driver side, #2 front passenger, then back and forth all the way to the back. Meaning 2, 4, 6, 8 would be on the passenger side. Is this correct? If so, and with a new COP in place, this only leaves the spark plug, right? Or am I maybe missing something.
Any advice would be appreciated.
Thanks,
Deke

No the Cyl numbers are 1,3,5,7 are on the pass side with #1 closest to the frontof the truck. 2,4,6,8 are on the driver side with # 2 in the front. My truck had the same problem, number six is usually the first one to go bad. That should take care of ur problem.

Passenger side: 1(closest to front bumper), 2, 3, 4(closest to cab)
Drivers side: 5(closest to front bumper), 6, 7, 8(closest to cab)
Firing order is 1-3-7-2-6-5-4-8

P.S. yes, i know this can be found elsewhere.
