A good test is to wind the shutter, let it sit for awhile (sometimes even
one minute is enough), then fire it with the manual adapter set to 1/1000
(and control knob set to manual adapter of course). if shutter goes
click............click, you've got de oily magnet.

Do you have a manual adaptor? If you have, does this happen in manual
as well? If it does, it may well be a sticky magnet problem.
BUT, if it it happens *only* in auto, it's very likely to be the ASA
resistor that lives under the film speed dial. It gets "dirty" over
time and the first few shots way over exposed like you are getting is
the classic symptom. Try turning the film speed dial to and fro
several times before making the first exposure. Does that alleviate
the problem? If it does, it's definitely a dirty ASA resistor. No big
deal to get it fixed as part of a CLA.
Let's know what happens.
