Default Major problem getting intake manifold off

The bolt on the back of the manifold on the passenger side, I cannot get to. I was able to back the bolt off almost all of the way, but the head is now under a wire loom. I cannot even see it anymore and I cannot touch it as it is too far away. I am really stuck, this is the first time ever I cannot do something. All of the pictures I have seen do not have the wire loom so it look easy. It is a 2007 made in the USA. I have end laid down in the engine bay with my arm going to the back of the engine, no luck at all. My fingers cannot even feel the bolt. I have attached a picture so you can see what I see. Any ideas. I have a car lift and looked from the bottom and cannot get to it from there either. Let me know what you think.

Default This is not for the "faint" of heart

Well I got the bolt out, took 10hrs. As you can see from the pictures there are brackets all over the coils. More has to come off. I have enough pictures and I will writeup a 2007 USA made if someone wants to do it. This is a 12 on a scale of 1-10. you can't get your hands in there and you cannot see at the same time you are trying to use tools. I finally had to be on my back in the engine bay and use a needle nose pliers and turn the bolt one degree at a time. That part of the job took almost two hours. In my opinion have the dealer do it. They will probably leave the bolt out and you can do it the next time. Everything else took 2-3 hours.

I tried this today as well. I was able to get everything but that third bolt on the passenger side and had to put everything back together without changing the plugs. Needless to say, it's a bad design. I guess that's why they advertise to change this out over the 100k miles. Yet, aren't Lexus' supposed to last well over 100K miles? Go figure on why they want to make this so difficult.

Anyhow, it sounds like there is no way to put the bolt back on. Has anyone tried removing the front windshield cowl on the bottom that houses the windshield wipers and upper strut supports? This seems like an option but a lot of work. I'll try to take a better look at this tomorrow.
