I just got this car with 210000 miles on it. The engine runs great have had it for a little while now, but suddenly wehn I let off the gas I feel as if the breaks are on. I have checked the emergency break, and that isnt it, I am not sure what else to check. And I dont want to take it in if its something that I can fix myself. The engine sounds fine, as it always has, the tires are new. I have replaced all of the fluids, and there were no alarms going off on the inside.?
