Resistance will fluctuate in TC are you locking your resistance ,I also space my coils because it works better in TC so that's not the issue, tried different brands of 28 and 26ga, screws are tight as can be, wires cut flush with the posts, but the ohms just aren't stable on any of my dna devices, so there must be something wrong with the atomizer itself, which isn't uncommon in clones by the way. I know people who have completely messed up coppervape hurricane V2s with multiple issues, I have 2 that are pretty much perfect (in which I also use a 0.8 spaced 28ga SS316L 3mm ID coil like I have in the skyline and there it performs without issue in TC).
Are you using a good quality wire , I use 316L , but theres many have problems with it.
So its recommend by many to actually use 304 Grade SS wire, has a higher TCR for better stability
Different TCRs. 403 is the most responsive to temperature changes, then 304, with 316 & 317 last.
316 is the easiest to find, and the default for most mods.
If you can't set a custom TCR,
But the 304 or 403 will give you a lot better stability in TC over 316-317L
Maybe strip your deck down completely , take out the posative pin clean check its Actually is Isolated + ect the usual maybe an oring or peak is missing ,
