I like A/C Delco in Chevys, Motorcraft in Fords and Champions in Chrysler products.

It came with A/C Delco which are designed by GM for your vehicle. NGK and Denso make good plugs. What code(s) did you get?

They said it was just a random miss fire code. It has new plugs wires cap and button. It's not platinum plugs though. Just regular A/C Delco plugs. That's why I thought about putting better plugs.

That vintage of Chevy had many issues with random miss-fires that are not easily found and repaired. I would do lots of research before I started throwing parts at it.

Did alot of research. Bad design with the spider injectors. Could that be my problem?
