Striped bolt.
Okay so I am changing my injectors and it seems simple but nothing that I have fits down in there. I had to grind down the sides off my torque bit just to get something to reach it. So once I got down there I noticed it looked like it was already striped to begin with so I started out very carefully in the hopes of getting it out and replacing it but then as I started turning it, it was really tight (like cross threaded tight) it was coming out but it was very difficult and then I got it to were it is now and it striped even more so is there any advice for this. I don't know what to do. Bolt extractors didn't work cause the stem isn't long enough to reach down there and nut extractors didn't work becuase they are too thick to get down toward the screw..

Grind/file off a bit of the torx bit tip (makes the teeth sharper) if its in any way damaged. Put it back on the bolt head and seat it with a light tap from a hammer before starting unscrewing again. If you got it to start backing out before, see if you can get some penatrating fluid under the head first and let it set for a while before trying again.

You may want to try some Kroil penetrating oil.
Only other option is a 12" drill bit and then try drilling it best you can.
Before I realized that bolt existed, once I removed all the other bolts, i just kept turning the plenum back and forth in an effort to loosen it from the grip. I only used a rubber mallet to start. Then I found the right torx bit.
It's definitely a pickle. Even my small hands barely fit under that side so I know your frustration.
If you have a long flat head screwdriver, then you can start hitting it at an angle as if your are trying to drive it. Be sure to put a quality penetrating oil on it. That should help free it.

Hmm I think I'm going to just cut the top of the screw off then I'll try the others if that don't work... on another note do you think that I really need that screw/bolt? I don't see why I need it.. plus I'm pretty sure it's defiantly cross threaded so I would need a tool to fix the thread tracks, which I don't have..

I don't know how you can cut it off, due to the location.
As far as needing it, its there for even compression of the plenum gasket. Either way, I would repair the damaged hole, and then try to bolt it in right. It's only like 10 lbs. or less to hold it tight.

Note of caution...
If you start driving at it with a chisel, take care not to CRACK the mounting area. It's only soft aluminum. To much and you will be looking for a replacement.

But what about the thread tracks now? What would yall suggest to fix the threading in the hole I dont have a heli kit or nothing like that. Is that the only way?

I can't remember what the size is, but running a well lubed tap slowly should clean it up enough. Glad you got it out. I took a grinding stone to the opening between the runners on mine so I had better clearance before I put the upper back on.
