On the MC at least, the window is 20 degrees wide at the distributor.

Due to bugs in the MAC11, the knock sensor code can get confused as
to which cylinder is which... even without throwing a hall sensor code.
(The hall sensor code is set in a different place to where it uses
it to determine cyl 1.  By the time it gets to setting the cylinder,
it may be too late and the hall window has passed.)
If the knock sensor code gets confused, you'll probably get
a 2141 code.
