I hate electrical problems. Been following the 6.2 since it came out and haven't heard of anyone else having this issue. I would assume it's a wiring issue. Check for rodent damage or wire damage in the engine bay

Computer and wiring

Checked wiring and cannot find any skent or broken.
looked under hood and dash.
Computer has a 2 year warranty and changing it back out.
Also going to replace the other 7 coil packs in case one is breaking down.
What lookskil is only 85,000 miles.
Someone mentioned a knock code, anyone know what that is?
My friend is the Ford truck service manager at local dealership.
Bought this motor because not supposed to have any problems or issues.
Said no bulletins about it.

Not a motor issue, it's an electrical issue. I know you said you checked all the wiring already, but I would check all of the chassis grounds and all the dead end harness connectors too. You know, all the options you wish you had but don't; Ford leaves the plugs in place and just caps them. The ones in the rear by the hitch are notorious for causing issues due to water intrusion.

no item made by man .. lasts.... and the reason for the warranty..

many 6.2L have gone over 300,000 miles without issues...

my 2012 XL 6.2L was a Fleet/Lease.... now has 166,000 miles.. its a good truck.

Flatbed ED,, on here.. went 418,000 miles on his 6.2L Gas engine... replaced engine and truck now has over 500,000 miles...

Ive read on here a few times now for these year trucks..when you notice electrical problems check the wire harness that located behind the parking brake to be sure the connections are firmly plugged in. Apparently they can work loose.

I would try to pull codes, instead of just shotgunning parts. Unless you just like to practice swapping coil packs and plugs. The main harness plug under the dash, next to the emergency brake is a known culprit for intermittent electrical issues. "Popping" the brake release, and letting the pedal spring up freely when released is known to cause this main harness plug to work itself loose. Causing all kinds of mayhem. Check this plug. When I use my E-brake, I only release it with my foot holding down pressure on the pedal, and slowly raise my foot (and pedal) while holding out the brake release handle.

And it's a truck electrical issue, not an engine issue.

Good luck.

x2 on the wiring harness. A friend of mine who also has a 6.2 had his start giving him vehicle computer related codes. His harness was loose on the bottom side of the plug.
