hello good day, i have a 2007 subaru impreza hatchback and anytime i come to a stand still on a hill or i have added passengers on the highway the car loses power and i have to give it more gas to go. i notice the eco light goes off and then comes back on after awhile.
i have changed spark plugs to OEM Subaru spark plugs
i have cleaned the MAF sensor
i have bought brand new 02 sensors
i have checked the fuel pump and see nothing wrong in fuel system
i have clean throttle body
i have checked catalytic converter and is still good
i check battery health and it is at good health but i still lose power sometimes even on highway driving when accelerating in normal or sport mode the eco/sport light would go off and come back on after awhile.
Even with a full tank of gas the car still loses power, and it was not doing this a year ago.
What could be causing the lose of power causes eco/sport light to go off on dashboard and come back on and lost of power?
