Bad injector - noisier with fuel additives?

[JeepSJ]

I have a tick/knock that I have pretty much narrowed down to an injector. Strange thing is that if I run no additives (like PS white bottle or 2 stroke oil), things are much quieter and I barely notice it. But if I add the PS or the oil, the thing knocks and rattles like crazy.

Thoughts?

Go through and loosen each injector line one at a time until you find the one that stops the noise. Yank it out and get it tested. You may have one that is spraying goofy or??????/

How many miles on the squirts ??

I can't understand how by adding 2 cycle it will make more noise? It should get quieter w/2 cycle.

I will not use any PS products again!

I'm guessing u have a mechanical pump, or? The DS4 you can shut down each injector to find the bad one in most cases.

When u crack each line be careful for the IP pressure can force fuel into and under your skin.

Good luck!
