I am facing a problem with my corolla 2009 mileage around 115,000 and car is on petrol. the accelerator suddenly stops working and I have to press the accelerator to the floor for the car to pick its RPM. Along with that the check engine light would turn on. Once I turn off the car and turn it on again the problem is gone but the check engine light would still remain and after I travel a while the accelerator would again give up. After having this problem for two days one morning I started the car and the check engine light was gone and the problem was also gone but then again in the evening the problem started again. Any help would be appreciated.
