1996 mazada protege. Has a hard time accelerating especially up hills. You can floor it and it just struggles getting up hills and such. It can do it just not quickly. However I discovered recently on a higway had the cruise set at 70 and hit a big hill that I know it does not like, it will generally drop to 55 getting up it. But this day with the cruise on it flew up the hill. Rpms went up, they never go up when I floor it, it just bogs down and struggles. But this time the car shifted and the rpms went up And the car flew up the hill.
Edit: this is an automatic transmission
