I bought this car september of 2007 with 102K and it had plenty of power, got great mileage (40+ mpg) had no problems at all, Now with 122K the power is gone but I still get the same mileage the car still runs great, I still have the same results except for the power, I have changed the plugs but couldnt tell any difference. Does anyone have any idea what happened to my power? Thanks for any help.
