Im back...
I don't even know where to start. I am getting "shift lever malfunction" when the transmission gets up to 3rd and 4th gear. I do have a new battery registered and coded to 90ah agm. I also changed all the fluids in the front, rear, transfer case, and trans. I thought I was leaking trans fluid through the mechatronic sleeve causing the codes, so I dropped the valve body and changed the mechantronic sleeve, along with all the seals under the valve body.
I also recently got codes for lean, which after smoke test, was leaking air from the disa and the valvetronic unit. Valve cover also semi newly replaced. I also got a new misfire on cylinder 1, moved coil to two, got misfire code on two. Changed the coil yesterday. Not sure if faulty coil in cylinder 1 is any clue to this?
I also now have a new loud clicking noise coming from the back left tire. It seems to quite some after picking up speed. (Driving in circles does not make the noise.)
So I guess my biggest concern is the "shift lever malfunction" and the clicking... IDK at all. All this seemingly happened at once, maybe from the cold?
Never did "check continuity between the plug and the DDE harness" as stated by crystalworks.
Here are the codes from my last few scans.
