when driving the car feels like it is surging as if someone keeps gently touching the brakes. mostly slow to medium speed even when on the daily 1 hour motorway commute. struggles terribly on hills or long slopes. no warning indications on computer or warning lights. oil & water ok new plugs recently but the car is severely lacking any real power.have treated with petrol injector treatment in full tanks but litle improvement
any clue would help please
