Well, last night it was nice and cool outside and my car ran perfect. It was a little rich when I was cruising nicely but it ran perfect, pulled hard as fawk. Now, its pretty hot outside today, and at partial throttle my car sputters. But at WOT, its perfectly fine. Anyone know what it can be? just the warm weather or what? thanks

 

^ same issues, happens randomly seems to have to do with outside temperature
