So I bought a 2004 Grand Prix GTP Comp G a month ago and every time I start it, it dies. But when I start it, I can give it a little rev and it will run just fine. Anyone know why it does that? Right now, it's in the shop getting the tranny replaced but it was replaced 3 days prior to me buying but the tranny slipped and kicked out of gear every time I drove it. But can anyone help with the starting issue?
