The resistance of the coil is not the most critical thing, it is the inductance. There are several possible reasons your coil reads higher resistance, none of them indicating a failure. Two I can think of:
1)SAMS has a mistake
2) The coil construction was changed sometime during the production run to use thinner wire or more wire with a smaller slug
Since the oscillator can be tuned to the correct frequency, both the coil A18 and the 15 pF cap must be OK. Stop fiddling with this section.
EDIT: repeat the AFC alignment if you have turned A18 since you did it.
