Having an issue lately with my tune. Lately I've been having an issue with my truck. It only happens when it's a normal operating temperature. I turn the truck off, go into the store, come back out and start the truck and it will immediately die. And will continue to keep doing this unless I give it gas as soon as it starts. I have to maintain the idle for a few seconds and then it will idle on its own. But this doesn't do it all the time. Only sometimes.
