So i own a 2005 Kia rio. Recently my check engine light came on with the following codes p0700,p0726, and p0741. Shortly after i noticed my RPMs jumpin up and down whenever i let off the gas. Soon after that i felt a jolt and then the car began to accelerate extremely slow and seemed like it was not switching gears or something. I can get the car to hit up to 70mph at 4000 RPMS but it takes me forever to reach those speeds. Any ideas?
