4.6 running very flipin' HOT

[St_Brawler]

I live in Phoenix AZ, and it gets pretty damm hot now a days (110-118 degres) My motor gets HOT to the point that it's only one line from overheating. Taht happens if I drive more than 20min with the A/C on (not even blasting) Than if I have to stop at a light I get a nasty smell of gas (fuel) in my car. Anybody else out there with this prob, or some one that knows why it's doing this and how to fix it??? Pls. help this crap sucks..... cus when it gets that hot the car wont even take off, it gets stuck around 1,500 RPM and no matter how hard I step on it it wont do **** . I also have a dif. thermostat of 180. Thanks for all the help
