Angry Cylinder 5 Misfire - 2k Camaro

My 2000 Chevy Camaro (89k miles) has a check engine light on it that reads cylinder 5 misfire. I had a mechanic replace all filters, oil change, spark plugs and wires with AC Delco items (That apply). Still, after the tune up it still sputters/shakes on idle and sputters as i accelerate. I checked the ignition coils and all are reading about 5500 OHMS (Two are SLIGHTLY rusted). I ran SeaFoam through the gas tank also.

What do you suspect the issue could be? Ignition coil or other? My tech said he did the smoke test on vacuum lines and it wasnt an issue... RAH

Thanks!

I'd suspect an injector problem.

Swap #5 coil with another and see if the misfire follows the coil.

Then swap #5 injector with another unless you just want to replace it.

I'd swap the coils before you condemn the injector, but an injector is more likely than the coil.
