I replaced all 8 injectors roughly 90 days ago and now randomly get P0087/P0088 faults within the same drive cycle. I have 227500 miles on the truck. My truck is completely stock. I am looking for some guidance/suggestions as to what could cause this to happen!!
Where did you get your injectors?

You have to be careful about where you buy parts. There's a lot of crap out there.

Cleanliness is very important.

Especially when dealing with anything that opens up fuel lines or the engine.

I use rubber caps and sponges
