I'm not sure what happened, I was playing with the kids and goosed the gas on my truck to spin the tires 5-6 feet nothing major the kids just roll with enjoyment. anyway the truck idle swayed violently then died and died 3 more times immediately 'till I had to gas it to get it to start, idled like crap. Now it does the same thing every time I start it after it's at normal operating temperature. nothing has been changed, no codes, no idea. Please help
