a bad injector not only does sound but will also have a visual (white smoke) and physical (engine shake) from imprecise firing.
its not smoke but have a slight misd some times and its have a slight knock when accelerate! and i think me hear that the ip transmission sound is effected whit the miss knock

mabe its just my head[emoji23]

the knock is from the injector firing too early. ie. not holding enough pressure.
does the miss go away at higher RPMS or get worse?

Tomcat is right.
Could have a couple of weak injector witch would cause engine knock. Have you changed the IP on it yet? If you have put new injectors in it and retime the IP.

When I changed my injectors I changed the IP as well I have a little shake still but didn't have the tools to do the timing right.
