A better place to hang out would help more.

Zamboni, you need to hook up the E28 intelligentsia.  We are at www.mye28.com
and no one there is going to tell you to buy a new car instead of
fixing the one you have.  Even if this persistent moron follows you
there, he won't last long because we won't tolerate those who have
nothing but abuse to contribute.

As for the service manual, I cannot tell you emphatically enough that
the Haynes manual you have is crap.  BUY THE BENTLEY!  It will be the
best $40 you ever spend on this car.  Trust me; I've had four of these
(E28s) so far and I'm buying my fifth.

Been there; done that

A new car would be cheaper than this!

Okay, okay, okay, I think I got it!

I did replace several things...all of which needed a good replacing.

At first, on the advice of a mechanic I replaced the air flow meter.
Nothing

Coolant temp sensor: needed it!!!! Old one disintegrated.
Nothing

Thermostat, original!!!! Needed it!
Nothing

While I was there, several vacuum lines, one of which went to the fuel
pressure regulator...'cos it was all crumbly. I was thinking...low
fuel pressure?

I had already recently replaced fuel filter and plugs.

Cap and rotor...might have been original :-< pins nearly cut in half!
Pitted, horrible
Nothing

Rearranged various relays (fuel pump relay) if appropriate.
Nothing

It was still overheating from time to time... which corresponded to
its poor behavior.

At first glance it looked like the fan clutch was ok. But one time, I
looked at it, it didn't seem quite right. So in one of my southern
"Hey yall! Watch this!" moments, yet without any "y'all "to watch it
or apply a tourniquet if I was wrong...I stopped the fan blade with my
bare hand while it was overheating. Excellent, said I!. Well, only
after noting what a dumb a.s thing that just was. I put a new clutch
on it.

The temp needle is absolutely rock steady. It never goes above medium.
and it runs great! Better than before. I zipped around the
neighborhood, frightened the children, scared the pets, stunned the
farm animals. It wouldn't act up. I almost wouldn't have believed it.
I'm not disappointed. Everything I put on, it needed. Even the
previous air flow meter was the wrong part number. At least now it was
one from the same model!

Thanks to Bill for your input. I'll let you know if it continues to be
a lady or a b***h! LOL

Alright all ye who are strong in BMW-fu

98.4 percent of the time this car runs absolutely fantastic. The other
times it acts as though it is overheating then stumbles and runs quite
poorly. The temp needle climbs, it stumbles, won't accelerate, then a
few minutes later it clears up and again...runs great. I have replaced
the thermostat. I have, but have not yet replaced, the coolant temp
sensor. I have replaced the airflow meter, on the advice of a
mechanic. Fortunately, it was cheap...(EBAY) but it made no
difference. I love the car...It's in great shape...but HELP!
