Default Knocking noise out of nowhere

After sitting over night recently when I went to start in the morning, there is a (rattle-y) knocking noise started from the rear injector areaon the driver side. Not very loud, but not as slight as a tapping sound. Not bucking, but a very slight miss.Oil pressure is fine. Slight power loss. Is this a sign that the injector is bad? What do you guys think? Thanks

Clogged or you got water in the tank. Sometimes happens when it cools/heats up during day ect... Try some of that water remover for your tank...

What varsis said..

or..

1. Exhaust leak, check exhuast manifold for loose bolts or cracks
2. Loose Rocker
3. Clogged injector (run some type of injector cleaner or take it off and clean it) (or use seafoam)
4. Plugs are arching (causes missifres, and a ticking noise, and less power)

try to pin point the sound with a screwdriver or somthing long you can put your ear to.. check the vavle cover, exhuast manifold, injector, plugs, ect..
