I have an 08 fusion sel v6 running stock with 50,000 miles on it. My question is why does my car seem to run better when its cold like when I first take off for work in the morning? After a while of driving around or when it is hot outside car seems to drag. For instance in the morning on highway car seems to glide and cruise doing 70 mph with ease but later after a while and temperature rises car seems to drag and struggle at 70 mph. Will a cold air intake fix this? Thanks!
