Re: 99 vortec 5.7 issue???
my 99 5.3 did this, wouldn't start, and sounded like it was missing or dieing out, wasn't constant though just here and there it was the fuel regulater, dealership part cost me 65 bucks, mechanic put it in for 10 because he had the same problem and knew what he was doin and his boss made him charge me somethin took him 10 minutes to pull in shop and change. apparently common on these years and approximate mileage.
