Question

i need help with that mission i can survive until i get to the bridge. by than i usually have about 75% damage than that prick jerry martinez comes through with his hunter helicopter and starts shooting missles at me, by that time i'm seriously ******.
i know a few cheat codes but i rarely use them. does anyone know how to bring my damage meter back down. i don't thing it'll let me use the pay & spray on that vehicle or is there any way to get those two cars to stop followng and shooting me. i need help in any way i can get it. i will even accept cheats even though i know some of them right off the top of my head.
