Sometimes when im driving and the RPMs sit at about 1300 it starts sounds like it’s dying out that even my fiancé asks if im doing that it bounces from 1k to 1200 rpm until i give it more gas to get out of that rpm range.
What could the issue be? Transmission?
It’s a 12’ 3.6 with 81k miles. The transmission and diff fluids haven’t been replaced to my knowledge since i bought at 30k miles
