“Accelerator pedal that is too sensitive. With the engine running and I start to accelerate from stationary, the accelerator pedal has an initial surge in power that was not intended by user input. This could cause the car to be out of the users control momentarily and could cause an accident if the driver does not allow for this issue. I have run some diagnostic tools on this vehicle and can confirm the engine is not doing what the accelerator pedal commanded it to do. I can see about 1% pedal input but I see about 10% on engine throttle response. This issue is persistent. …”

I have about 75,000 miles and the problem has been ongoing for over a year. I have to add oil every week and if I forget, it is all burned up within 2 weeks.”
