I have a 1985 E28 with an M30 5sp. My motor hesitates throughout the rev range, and really starts choaking at around 4500 RPM.
To give you an idea about the condition of the motor, I bought the car about 2 years ago, and my valves were clacking so I took off my valve cover to adjust them, and to my surprise the head looked completely new. Even the cam, everything. Well to continue, I checked my compression, and I got as follows :
181 181 180 182 181 181 which I think is pretty good.
Anyhow, I have new spark plugs, changed my cap and rotor, and air flow meter (though, it isnt in my car right now, because it actually runs a lot better with the old one, no matter how the newer one is adjusted). Only thing that I haven't changed is the spark plug cables, and the ECU, but I had the ECU apart 1 year ago because my car wouldn't start because I had a loose solder in the ECU. That was fixed, and I had a good look at that thing, and it seems to be in excellent condition now. Oh, yeah, I have good fuel pressure as well, and all electrical contacts are clean.
I really want to know what I can do to this car to make her roar like she should.
If you show your BMW love, she will love you in return.
