My car is displaying the engine management light on the dash. To date my mechanic has replaced a pencil coil and cleaned the airflow meter. First he said it was the lambda sensor that was not connected correctly.
My car shakes and shudders on start up. Sometimes it revs itself to 2000 without me pressing the accelerator. When I take off the car has no power and struggles to go faster that 20mph. After approx 3-5miles it seems to jerk then normal power resumes.
Does anyone have any idea what could be causing this?
Thanks so much for any input.
