Over-acceleration Liberty 2004, help needed!
After being away for a week I was driving my Jeep Liberty 2004 (automatic transmission) yesterday, and it was like driving a wild horse! While the engine normally goes low with a nice grumbling sound, this time i would not go below 1500 rpm in neutral and park, and completely over accelerated by itself in Drive. It is mostly uphill but I didn't even have to press the gas pedal for most of it. Needless to say, my brakes were completely overheated at the end of the ride. Its a 30 min ride each way, and it didn't get better at all.
Can anyone tell me what may have happened? I live in Haiti, so the mechanics are not excellent so it would be good to have an idea of what's going on before I take it anywhere...
Thanks a lot!!!
