After going through these steps, the burnt taste should be gone or at least noticeably better. You want a clean, smooth draw that doesn't hurt your throat. If you replaced the coil, the new one should taste fresh after a few puffs. Your device should feel consistent throughout your commute—no sudden harsh hits.

If you have an adjustable wattage, note the setting that worked. For example, if you were at 25W and 20W solved it, remember that. If you're using a fixed-wattage device like the LINQ-SLIM, you can't tweak power, so focus on wicking and timing.
