ok, first of all, my mustang is a aode with only a cold air intake. i've noticed that whenever i first put my car in drive and push the gas, there's some hesitation in it going. i've also noticed it does this when i'm already moving and i floor it, it seems to choke before it down shifts and picks up speed. i dont know if this could be a fuel problem (never had the fuel injectors flushed nor fuel pump replaced) or if it could be something w. my throttle body..any suggestions would be appreciated...
