The fuel injector at Oreilley’s is an SMP and a good choice. The Acdelco is available on Amazon, but at a horrific price.

For whatever reason, it’s again available on GM parts sellers, but for anywhere between $500.00-800.00.

That's the part that goes in the brake booster, not the part that goes in the upper intake manifold.

Thanks, for some reason I just could not find that one at all, and was only ever finding the one that goes in the booster itself. That'll help a bunch.

Yup, had already ordered that one. Ordered the booster vacuum check valve as well, since it's the one that came in the truck, and it won't hurt to replace it. Since I'm probably gonna replace the whole vacuum line anyways, since I'm willing to bet it's not gonna wanna come off the fittings, being 28 years old and all.

If that fitting or booster hose was bad it can make it run rough.

 

[Saren42]

Yeah, it's not just rough though, it's very solid miss fire on a pair of cylinders, iirc, it was cyl 4 and 6, even after doing plugs, wires, cap, and rotor (those all did not have many miles on them, and looked fine, but replaced anyways, just in case). Which, is probably then the injector spider. But I want to fix other things before I tear into the intake to replace that, just in case it is *just* from this vacuum leak.

 

[Caman96]

Hopefully the booster itself is not bad, they do commonly fail, but not to bad to replace.
