Question about Cars & Trucks

While you are in there check the intake boot that is Y shaped for cracks, it's prone to fail and will mess up your idle too.

the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.
