Im going to be out of town a coulple of days for memorial day, but when I get back I can run more tests.

It is just so odd to me that this would start now, because the engine has been this hot before. I guess it is just because it is so hot outside?

Ill clean my cables (again) when I get back and see if that does it for me.

I would really like my car to be reliable in any weather conditions.

Could it really be the battery if I just replaced it less than a year ago?

Is there anything else that I can test before spending money?

What is it that I should do?
