quick ignition coil resistance question

My repair manual says that the secondary resistance on my coil should be between 10.0k and 12.8k ohms. My car, when warm, tests in at 14.7k ohms. As far as I remember it tested within range when cold--will recheck. Soooo time to replace???

(primary and terminal to casing resistances within specs.)

1995 altima gxe auto. 207k miles with a stumbling problem that gets much more evident when car gets warmed up.

Thanx

sounds like a good guess/deduction - coil starting to fail - as the temp increases the
stumble increases.
don't know of any more diagnostics on a 95 model besides - substitute a known good one for a suspect bad one
