Could be be clogged fuel filter or air filter or poor output from fuel pump. Low fuel pressure etc will cause it to "starve" for fuel. Clogged air filters will do similar thing causing it to choke for air. You said it loses power, does that mean it stops running and the engine dies or is it just not giving you as much acceleration as you need.

Could also be the drivetrain like torque converter or transmission depending on the model if it is automatic. If it is standard then it would not sound like a drivetrain problem, my first suggestion if to get your fuel filters cleaned and then have a fuel system cleaning done.


They will physically clean the throttle body and add a solution to the intake while it is running as well as pour an additive into the fuel tank.


First things first, fuel system cleaning, then fuel filter/s. Then check fuel pressure output.

You describe this as an acceleration problem however, if the car does throw a check engine light it should be recorded in system memory so it can be pulled by scanning with and OBDII scanner. It sounds as if the car is being starved for fuel on acceleration. Check the fuel lines for kinks as well as check the fuel pressure. The problem could be a faulty fuel pump that has yet to completely die.
