Thank you for the finer details. I knew about the nominal flow if they couldn’t be matched but wasn’t gonna do anything until pulling and seeing. The lube was the main question and I seen where people had, but I wanted to know what exactly gm wanted there. I would think the lube would actually attract more carbon than without it over time. This helps a bunch thanks again!

So I got a l86 and got the notorious P050d code. This only happens when it’s in dual pulse mode on the cold start. I’m getting prepared to pull the injectors and get the part number to order. I’ve seen several videos and guides of people installing these so I know basically what to do but have a couple questions on little things. GM does not say to lube or put anything on the seals of the new injectors. I’ve seen where people have and people haven’t. Any advice on this? Also I already have the too high pressure lines. I don’t need to replace the 3rd low pressure line right? Is this somthing you’d replace anyway. I’m going to do all 8 injectors at once.
