Sounds like a throttle position sensor or mass airflow sensor is at fault.

I suggest you do not guess as you need specific info. Have a mechanic code the car and see what the car is reporting. Even then it takes a good one mechanic to advise you on repairs and associated work needed. OK? Many things are related. Have the car looked over carefully. Best of luck.

Hi, You need to clean the throttle body and carry out basic settings, make sure there is no air leaks and that the dipstick tube is not broken. This should cure your problem Regards Lee
