Hello Bigcoupe, I've been having a strange issue with my 1989 635. It all started when I was driving down the road and suddenly the car would not take any load, but it wasn't misfiring. So I stopped and fount out that the MAF was unplugged. However even after I put it back in it still was running poorly and would not take even quarter throttle.
So the car is now sitting on the lift and I've done a few checks- I've bought a working MAF from a junkyard E34 535 (b35 engine) and no luck there. I found that for whatever reason the car would sometimes start with the new fuel filter on backwards. The distributor rotor had a large amount of corrosion on it so I am sourcing out a new one. But in the meantime I can't tell if it is a fuel problem or a spark problem. The car has plenty of fuel pressure, so perhaps it is a spark issue.
Anyone have any expirence with the B35?

A little late but I might as well update this in case anyone has seen this and wants an update. The issue ended up being the Crank Position sensor. Fairly common issue and in fact I didn't even have to replace it- the bolt came loose and had to be retightened.
