1995 Pontiac Grand Am No EGR Valve?

1)When I accelerate fast it makes a strange wwaaa noise.
2)after driving for a bit if I have it in D when I come to a stop coming off the freeway it dies, fires right back up but as soon as I put it in any gear again it dies. To keep it from dieing I drive around city in 2, if I go on freeway I put it in D, and when I come to a stop off an exit I put it back into 2 when I have slowed to about 30-40mph. That has kept it from dieing when coming to a stop. I almost want to say it dies if I slow down too fast but I'm not 100% on that. Now, again if I come off the freeway and come to a stop in D it dies, so I start it up put it in N and when the light turns green I rev it up and throw it into 2 and it clunks and slower than it should it starts going, with that strange sound from accelerating fast. I thought it might have been the EGR valve needing to be cleaned up or replaced but I did some research and the 16v Qaud4 DOHC 2.3L engine does not have an EGR. Any thoughts or previous experience with a similar problem would be appreciated.
