ford contout surge
 

foes anyone know what may cause a 1998 fird contour se. 2.5 v6 air auto all power. the cars engine seems to surges almost constantly (not sputter or spit). the dealership said it was normal but i think different. they also said that the accumulator was going bad, so the ac stopped working[:-] so until i can get it fixed the heat and air stay off . any ideas
