Hello. I have an 07 Maxima. Runs great except when it gets really really hot in the summer. If I leave it idling for more than 15 minutes in the summer with the A/C running and then turn off the car, if I turn it back on with 30 min or so, the car starts to run really rough and runs really rough. Why? I changed out the Spark plugs with great OEM ones and have a new air filter and I used a fuel system cleaner and my A/C is charged correctly . I don't get any check engine lights. Pleas help. Also the car starts to over heat while it's running rough like this. Never dose it exsept in the summer.
