Welcome to the forum. It sounds like you have a dirty Idle Air Control motor. To clean your IAC motor, do the following: First, buy a can of throttle body cleaner and some paper towels. It should be held onto the side of the throttle body by two star-bit screws. Remove them, and unplug / remove the IAC motor. First, clean the hell out of your throttle body and the IAC motor cavity left by it when you removed it. Pull up the throttle plate and stick some paper towels in there, and clean the living hell out of the inside of your throttle body and IAC motor cavity, repeatedly cleaning / wiping with throttle body cleaner until everything is clean. Remove the paper towels (make sure you don't leave any in the throttle body!!!). Now time to clean the IAC motor. Make sure you only use throttle body cleaner on the spindle itself - it's too harsh to spray directly into the motor. Just keep spraying / wiping the spindle, and especially the rubber part at the end. After this is clean, put everything back together, and you should be good.

Welcome to the forum montinko. From now on, please make a new thread regarding your question.
If your car is not starting when it's hot, my first guess would be your fuel pump is going bad. Can you give any more symptoms?
