I had 99' Pontiac and replaced lower intake manifold gasket so I dont know this will help much but here it goes. First off you have to go to autozone and buy one of those repair books for your truck. Second you have to follow the instructions for replacing a intake manifold. Just remember *important* to mark all hoses and all connections properly so you'll know where they go back in place. And dont forget to torque the manifold following sequence and in/ft lbs. I think you have to take off your fuel rail and injectors, might be a good idea to replace the O'rings on those also. Alternator and Power Steering pump come off to i believe, just follow the instructions not that hard should only take you bout six hours messin around with it. Good luck
