99 yukon
350 Vortec
Service engine soon
Computer scan shows cylinder 5 misfire.
Change plugs, wires, distributor cap and rotor. About that time anyway. Still throwing code.
Hook up in real time. Complete misfire at idle. 0 misfire over 2k rpm. Looking at a vacuum leak? If so where to start. I know nothing about the vac system.

I'm pretty sure the 350 has a spider injector like the 4.3 Vortec. They're notorious for failing and causing issues.
