1998 Nissan Maxima with nasty sounding rattle

Other than this rattle my car has been in fine working order. I have done all of the preventative maintenance. It has 180,000 miles and started making this rattle sound only a few minutes after I drove over a small flat object with my tire. My car has a timing chain that uses a tensioner to keep it from having too much slack but those tensioners can fail from time to time. Before just replacing parts here and there I would like to have some other people's perspectives on what may be causing this noise. Any suggestions would be greatly appreciated.

Also, it spit out two codes:
0608 - Cylinder No. 1 misfires (many possible causes listed but I wouldn't be surprised if one of my injectors went bad as 1 or more of them have been making more and more noise over time).
0304 - Knock Sensor; an excessively low or high voltage from knock sensor is entered to ECM; possible causes include short in Harness or Connectors or a bad Knock Sensor.

Possible causes I can think of:
-Rod knock
-Bad rod bearing
-Foreign object in valve train
-Bad timing chain tensioner
-Bad sensor which could be the camshaft position sensor, the crankshaft position sensor, the knock sensor, or an oxygen sensor.
-Bad fuel injector

my car is kinda having the same problem, my car is the nissan maxima sl 2004, it has 99k miles on it, not at 100k yet. but i was wondering one thing, cause it does sorta this kinda noise for like a minute when i start the car.. but when i drive it for like lets say 2 minutes , and i stop and go outside to check it out there is no noise like it at all, it confused me, i dont want to start checking the timing chain cause that will be a long time to get down there to check it out.. so idk..

[diederich0017]

if it is a quite continues nock it is a lifter rod, and if it is loud like that it is a timing chain, dont run it anymore or ull lose the chain and smash in ur valves, and ud be better getting a new AMERICAN car, after that.
