Car has 83,XXX miles. just purchased use on 4/20/2021. Driving to interview about 65 MPH and then the car slowly just stopped accelerating. There was zero spudder or stall, it just slowly stopped going. pulled over right away and it would not start. Had it towed to my friends and hooked up a code reader and it said $E8 and $E9. I have no clue what to do from here and I'm not trying to spend a lot considering I just paid cash for this vehicle. Any help and guidance would be greatly appreciated! Thanks for any help I can get! Have a good day everyone.
