Hey guys and gals

Having a problem with my 1uz-fe (stock) in hot weather.

Okay heres the problem.

1.) Starts a little rough.
2.) Idles at 1500rpm.
3.) Tries to die when the gas is pressed.


This only happens when it's hot outside. Don't think it's a fuel system issue. Could a problem with the vacuum hoses cause this problem? I'm not too savvy with motors so you all's help is great appreciated.

Thanks
