Here's my rule of thumb: if you've warmed the device, primed the wick, adjusted airflow, and taken a few steady puffs, and it still tastes weak or burnt—stop. You're not going to fix it. The coil is likely burnt, or the e-liquid is just too degraded.

Burnt coils taste harsh, like something is burning. If that's what you're getting, retire the device. Don't try to poke holes or disassemble it—that's dangerous and can cause leaking or battery damage.

When you're done with a disposable, recycle it properly if your area allows, or dispose of it in accordance with local e-waste rules. Don't just toss it in the trash if you can avoid it.

And remember: a weak-tasting vape in cold weather is common, but it's not a sign that it's time to quit or that your device is defective. A little warmth and patience usually does the trick.
