98 Chevy Van starts like it is supposed to when COLD. Turn the key and it starts without giving it any gas.
After it has got up to operating temperature if you shut it off and restart while it is still hot you need to give it gas to get it going and then it dies immediately.
To start when hot you must give it gas for about 5 seconds and then slowly let off and it keeps running fine. It does not die at stoplights or while you are idling. Just a starting problem when engine is up to operating temp.
