It is freaking me out. I know about hesitation problem when accelerating but this is when just driving at the same speed whether going 30 or 60 miles an hour. I have had transmission checked, it is not that. I have had several things replaced, gas cap, O2sensor. Does anyone else have this problem? Or know what the heck it is? I am getting stressed out over this. I am about ready to call it quits on this car.
