When I got this car 2 weeks ago it ran perfectly. I put some STP fuel system clener in it and the check engine light came on. When the vehicle is cold it runs perfectly, but when it gets up to temperature it stalls. When I press the gas it mists and shutters and I have to give it more gas and it'll finally catch. It has that 4.3liter V8 in it. Is this a fuel or air problem? It doesn't happen all the tim, just sometimes. Any suggestions? Thanks
