I started to recently have problems on my 2018 gt sport. Sporadic rough idle, fluctuating rpm while idle mostly when on the colder side. Jerking while accelerating especially uphill. Rough 1st to 2nd gear. Loss of power when I gun it from 0. No check light, 34k miles. I’m thinking it’s some sort of sensor? I should be covered under warranty if I’m having engine probs. Any help is appreciated!
