06 E53 3.0 P0302 303 304 PLUS INJECOR CIRCUIT ISSUE

Curious,

Having read through this whole string, it appears there are some knowledgeable people on this forum about this issue, but it is a old string, so I don't know if anyone solved problem or not, it was left hanging with an argument. I am somewhat a new poster, so I will give it a try.

I have 155K on X5, it started with an occasional misfire and injector circuit signal missing codes on #3 only, so I put some fuel injector cleaner in tank since it was very intermittent, low speeds and high speeds, no safe mode issue. I thought it was better for about 500 miles, but then I got same codes on 2,3,4 at same time and engine now barely runs obviously on only three cylinders. Codes come up for all three, so I was curious, what can cause this issue?

I have checked wire harness issues, connections, etc, and having this multiple issue now, even though I purchased new injector, I am now thinking it may be something else given it is not just one cylinder any longer. Is there a ground issue? The MAP sensor would be more random to my knowledge, not consistent to only three cylinders, so I don't want to throw parts at it just yet. The same is true for 02 sensor issues to my knowledge, so I am stumped, fuel pressure is fine, so I am stumped, any ideas out there?

Thanks,
