Reads different resistance than the coil

Mods are not ohm meters. I think, that every mod I have, tells different resistance of the same coil.
If you want a decent coil ohm meter and don't want to spend hundreds of dollars on it, buy a GeekVape 521 Tab Pro Resistance Meter Tester - $39 at Fasttech.

While it's true mods aren't 0hm meters,these days they're actually precise enough to use instead of an 0hm reader.
Furthermore, when you have 2 coils your resistance should he half of what the coil is (in this case the coil is .3 so 2 of em makes it .15)
Also note that coils always have a slight difference in 0hms but this is not normal to me.

Unfortunately all i can tell you on this is check your connections make sure there's no hotspots on the coils. If those coils are stainless a resistance jump while vaping could be normal as stainless has a tendency to do such things.
Factory-made coils may have an "acceptable" inaccuracy of +/- of 0.2 ohms. For example, the box or package says the coil should be 0.3 ohm, but if you measure it with an ohm reader or resistance meter in a regulated mod and its off by 0.2 ohm its considered to be within "acceptable tolerances" by the manufacturer.
To me, that may be acceptable if you are using a regulated mod because the regulator chip won't fire if the resistance is too low to be safe. However, that would be unacceptable if using an unregulated mechanical mod because 0.1 ohm is probably too low for most batteries. A mech mod doesn't have a safety feature to prevent firing an unsafe coil because it doesn't have a regulating chip.
Coils will also gradually increase in resistance as they age and collect byproducts of unvaporized sugars and flavoring agents.

What mod, tank, and coil. Hard to troubleshoot without that info.
When a coil is fired, a specific part of that coil may have what's called a "hot spot", which is a short. That spot will glow much brighter than the rest of the wire. Normally, a coil should start to brighten in the middle of the coil and spread wide in both directions in brightness.
In the above video, the user "plays" with the coil using tweezers. Notice that the tweezers are ceramic tipped. If you touch the coil without ceramic tweezers you'll create a hard short of the battery when you fire the coil.

A hot spot (short) would show as lower resistance (ohms) not higher. If it is multi-coil I suspect one of the coils is broken or not making a solid connection for some reason. The additional resistance could also be in the 510 connection (thread connection between atomizer & mod) try cleaning both with alcohol.
@Ethan diy By the way, I was assuming you were asking about RBA (rebuildable) coils.
You would never dry burn (fire) a drop-in factory (clearomizer) coil without there being some e-liquid on the wick, or you'd cause a flame.

The coil wouldn't happen to be a SMOK branded one, would it? I rarely use drop in coils anymore but they can be all over the place some of the .15 coils would be .13 to .20 and they would also (as coils do) change resistance during use, generally up so .15 would become .18.
Drop in coils are mass made and cheap (to make, not always to buy, lol) so QC can be hit or miss. So your coil could just have been part of a bad batch or maybe they make a .9 coil and put it in the wrong coil head and/or packaging.
It could be a multi coil head and lost a coil (or more).
Well, technically a RTA coil is considered "rebuildable". But you can purchase "pre-made" rebuildable coils for RTA, and I'd consider those "drop in".
