Not sure whats going on car runs great but at least once a week the car doesnt want to start it will start and run very rough for about 15 seconds even when you try to give it gas it unresponsive it stalls then will just crank if you leave it sit for 15 to 20 minutes it will start anybody got an idea thanks in advance

 

First check for codes, but I suspect a dirty IAC valve (motor). Code for this is P0505. The pintle can be cleaned , but that fix is usually temporary at best. If the IAC is dirty the throttle body and MAF sensor probably need to be cleaned too, and you may want to replace the PCV valve.
