*Truck idles good, no ticks or funny sounds, idles very smoothly.

At shop.
Compression checked good.
Injector GOOD.
Coil GOOD.
Sparkplug GOOD.
Computer shows constant misfire.
Currently checking electrical... will update...
I asked about possible broken valve spring on that cylinder and he warned it was a "massive job".
I called dealer and they quoted $372 labor for intake side.
