Welcome to the forums, although i would recommend reading the stickies and making yourself familier with all the sections, this is for intros only and you won't get much traffic to help you with your tech issues. Post your problems up in the General Tech threads, thanks!
 
welcome. reads the stickies! change plugs and wires and fuel filter. make sure terminal tip of coil aren't corroded. no autozone wires! use ac delco or high name brand.
