I recently bought a toyota corolla 2011 s from a local dealer with 80,000 miles on it. In my test drive everything seemed normal and was satisfied with the deal. But on a recent trip when i actually drove this on international highway my car seem to have some problems.
Once i reach 45 mph the car doesn't seem to accelerate the way it should.
No matter how hard you go on the gas pedal the acceleration is dead slow.
I don't see RPM's going up as well.
When using cruise control and pulling the lever for acceleration RPM goes all the way up giving a sudden push to reach the desired speed.
What could be the problem and how much is the damage?
