After a few hours of testing and pondering, I discovered this, valve making contact withe piston. Cylinder 1 and 3, under the intake, had a constant misfire so I fished in a bore scope and seen that😲🤦
Not a happy customer!

2011 Toyota camry 2.5, Cylinder 2 misfire.
Customer was told, you need spark plugs and coil. So, they were changed by a shop.
Misfire continued.
I get it and found that Cylinder 2 injector was leaking. Pulled all injectors and cleaned them, replaced o-rings and cleaned out carbon and added sea foam cleaner.
Now, it's running even better. No misfire!

2015 Dodge Durango sxt 3.6l
Misfire cylinder 3
Several shops said blown head gasket. Did a leak down test, I got no signs of air leak. Pulled the valve cover and discovered flattened cam-lobes. Replaced intake camshaft, rockers and lifters. End result, car runs good!
