Every time I come to a stop my car dies

it appears you have electronic throttle control. any applicable trouble codes, relating to that system? clean the throttle bore and around throttle plate, don't force the throttle plate. your idle air is electronically controlled.

Sounds more like a vacuum leak. Is it hard to start when it knocks off?

Have the fuel filter checked out.

my monterosport 2001 runs great till you come to a stop sign the rpms drop and it dies start it back up revs itself and rpms drop and it dies. we can start it up rev it and it clearsup and idles but later on when you come to a stop it dies again we have cleaned the egr valave and still same thing could the tps be the problem or what?

1 or more plugs may not be seated well or just a bad plug. Also sometimes can get debris down in spark plug socket

This is a known issue for your model and for GrandAm's. Best to take it to your dealer.

replace your pcv valve

Try adjusting the idle and changing the fuel filter.

I cannot see how adding a fuel additive would help to be honest. I would be looking for a split or leaking vacuum line, I have even seen a leaking evap canister before that caused a similar problem. Does the engine pull clean and strong when it is warm or at cruising speeds? Does it feel like its running lean or misfiring?

my favourite mantra this time of year. check the ignition relay... it is often located in the engine compartment fuse panel.... another consideration is you may have a shorted wire or poor connection in some part of the distributer cap or coil. can't recall if they used coilpacks that far back in the model years but that's a suspect as well.
