    most of the time when i start my car it will rev really high 2500-3000 rpm some times 2000rpm. but then it drops down and stalls (not everytime but more then sometimes

    then on other start ups it starts like normal 1000-1100 rpm then drops down to around 800rpm

    any thoughts on the source to the problem. its a 97 gp gt
