I've got about 3,500m on my '19 Bullitt, and may have encountered a potential problem: On a hot day--near 100degF--sitting at a couple stoplights, the engine started running noticeably rougher. No movement on the tach--I think the ECU will keep idle steady no matter what it takes--no CEL or other indication and it didn't threaten to stall, just noticeably rougher than usual. This happened twice, but once I got moving it smoothed out. It's been even hotter--105 a couple times--and I didn't have this issue. No 'ticking' or 'rattles,' at least none that I've noticed and I'm pretty sensitive to engine noise.
Anyone else seen this behavior?
