my car is acting wierd in the heat..

[nigel1]

summer is here and the heat is making my car act stupid.

when I leave my car in the hot sun for a while, or shade for that matter too, I have to turn the keyon my ignition at least 5 times before it turns over. it starts fine after it turns over. the way I know its the heat is because at night when its cool outsuide it turns right over on the first try. also when I park in the garage where its not that terribly hot it starts easier like on the second time usually.

I have no clue what to do. I didn't see anyone else having this problem on here when I searched for it.

any advice would be great. thanks!
