2006 BMW 325xi 325xi

Upgrading to a new car and wanna get rid of this to clear room in the driveway. Preferably to someone who knows something about cars and can work on them. It has something going on when going above 70mph on the highway where it seems like the car loses power for a second and jerks a bit as the rpm’s drop for a split second then come back up and I cannot figure out what is wrong with it and am sick of trying. Tried taking it to a shop and they said the intelligent battery sensor was the cause so I replaced it and it is still happening.

Car is beautiful and runs super well and smooth when it isn’t having issues and is so much fun to drive. I am just not a car person and am sick of trying to figure out what is wrong with it so I wanna sell it to someone who can figure out that issue and have a good time with it. 

Brand new wheels and tires within the last year
Wrapped the car with a matte green wrap recently
Tinted the windows
Muffler delete
Replaced the IBS
Valve cover gasket replaced


Also will include in the pictures what someone on FB told me the fix to the problem with the car is and if that is the case it’s a super easy fix.
