2G Testing coil pack, readings

[95gsttsi]

so i tested my coil packs the other night. and on the one that keeps going bad 1-4 the reading went from 13.08 to 13.32 in a matter of 5 minutes. while the other coil pack 2-3 stayed at 13.08. what could be the problem?

It's still within the good range of 11.3-15.3k ohms. Maybe you just weren't getting a good connection when you were checking the coil. To me it doesn't sound like you have a problem with either of the coils assuming the primary resistance checks out within the specified range of 0.70-0.86 ohms as well.

Are you having a problem after the coil gets hot or anything? Or are you having a problem all the time with the 1-4 coil pack? If it does it when it gets hot I would try testing it when it's hot or whenever it is exhibiting it's issue to see if it will test out of the specified acceptable value.

Good luck

FWIW, testing a coil pack with a DC resistance check won't tell you if it is good; only if it is bad. You can have a bad coil that will pass the standard resistance check all day long.
