Someone please help

Yesterday I brought my 05 XT in for a break issue, turns out it was something a simple as the shop before not connecting some vac lines into the break booster. Well Pomps also found a fuel injector loose so they tightened that and the fozzy was running GREAT!. Fast forward about an hour and my gf and I are driving to a local town about 125miles from us to pickup a down pipe for the fozzy. Well on the way there, I start hearing this sound ( similar to the sound someone would make if they were to be gasping for air ) and then it would go away, it was very intermediate . We stopped I filled the car up with 93 and continued on our way . About 2miles from the gas station the same gasping sound started right back up again and the check engine came on . I ran the codes ( have torq for my phone ) and it showed up as a crank sensor bank 1 ( not exactly sure on the code ) . But now I hear almost a rattling sound along with that gasping sounds ( intermediately on both ) and for whatever reason the light hasn't came back on but the sound is still there . It seems to only happen if I pass 4k rpm's , otherwise it seems to idle and run fine. I had a mpg tune on the car via my cobb I got of a member on another site , and put it all back to stock. I wasn't beating on the car nor have I been since I got it back I've been trying to work all the issues out of it so I can have a reliable car to drive daily and mod as I please , but that hasn't been the case it's been one issue after another .

Can someone PLEASE shine some light on the issue, I'm at the end of this road with this car, I love the car but it's been such a rotten egg that I'm honestly at the point of selling it , taking a loss and just walking from it . I have a baby on the way and reliability needs to be the number one concern and it has been everything but that .

If need be I can post a video of the exact rattling sound it's making maybe even the *gasping* sound it's been making as well if need be. But the car has been parked the moment it happened we turned around and just went home and I drove at 50mph if not less to avoid hearing it do that again. It does it no matter if I'm in drive or park .

Thank you
