WHAT DO I DO NOW

1996 GMC C1500 • 261,701 miles

I got a 96 gmc 1500 with a 4.3 v6 I replaced intake gaskets last week then I started skipping so I then checked and changed the spark plugs, wires, cap, and rotor button and it still hasn't solved my problem.

Did you remove the spider? If you did. Double check it for the injectors.

Make sure there are no vacuum leaks at the upper intake and the lower intake.

Did you verify the spider under the upper intake? Did you have the spider out?
