I am somewhat at a loss for the moment, nothing really standing out. There is an obvious Lean condition, but what came first the chicken or the egg??

So is the Lean condition a true Lean condition or is this due to Misfire with Fuel Cut off and is one or more cylinders pumping a lot of air/oxygen into the exhaust stream??

Shooting from the hip here, what is the status of the fuel pump relay? If it is original, I would replace it. Not 100% if the E53 horn and fuel pump relay are the same, if they are, swap them and see what happens.

I am tied up the rest of the day, will think about this and look over again in the next few days.
