When the weather is in the high 80s or 90s, my car won't start. it turns over okay; the electrical system/battery is fine. after about 20-30 minutes or longer, the car will finally start but is not necessarily okay for trips. at the first stop the same problem may or may not occur again. when the temp goes down in the fall, the car is fine and runs beautifully. at first i thought it was a problem with my car only but have seen other complaints about this same issue. i think the issue is caused by something in the fuel intake system but have no evidence to prove this. for about four months of the year i am forced to do all my shopping in the very early morning or at night and still have the problem sometimes then. *tr
