Camaro Problems?

Could someone please help me! My 98 Camaro is acting crazy! I had a diagnostic ran on it and it called for the TPS and the MAF sensor to be replaced. I replaced them both today and that did not fix it! What else can it be?! When I give it gas it will just act like it is going to die on me. It will shimmy and shake like a vehicle does when it is out of gas! What else could it be. You can reply back to this answer page or email me at bluegrfirearms@yahoo.com Thanks so much for all of your help :)
