Sorry I couldn't find a forum for this problem but you guys seem to be able to figure anything out. I have a 2001 Grand Prix with a 3800 with a reasonably fresh tune up and when starting up cold it starts fine. When warm it cranks for a bit then takes off and imediately stalls. When you crank it over again it stays running. Gets good gas mileage and the fuel filter is new as is the plugs, wires, air filter. About 70K on it. No SES lite. Please help me before I kill my starter.
Thanks

 

someone pls move this to V6 tech for me I don't know how
