ice pick Fix maybe?

i know there is prob a ton of other threads over the same thing but i searched around and i hope that the 'ice pick fix' is all i need. i noticed today my truck was missing and my insight was saying one of my injectors was bouncing between +10-13... i think its injector #7. i remember checking during the summer, maybe 4k miles ago and they all looked good, so it happened fast if the injector really is bad. i only got 105k miles and she's always ran good... I have a few other questionable injectors tho... attached pic of my balance rates

I would try the ice pick on #7 first, doesn;t cost anything to try it, also check your FICM harness where it is zip tied to the alternator bracket.

FICM harness fix and ice pick all the injectors for sure, then run 32oz Diesel Kleen in a full tank and check again.

Post up your balance rates again after that and we can help from there.

Do all your injector connections and use a little dielectric grease on them before reattaching again.

You don't litterally need an ice pick, just a small set of picks from the hardware store.

Something like this:

Amazon Amazon
