Hi my 2015 kia Optima on 08/07/2020 I put the recommended gas in my tank and then got onto the interstate after about 5-15 mins it started loosing power and I could no longer accelerate past 60. Also now when I start driving it jerks really bad and won't go past 2 on the rpms. When it jerks I'm assuming that it is the gears trying to change. Also my check engine has acted weird ever since buying this car it comes and goes and just recently is when it stayed on and when this happened it began flashing when the loss of power and couldn't accelerate properly issue began.
