I have a 1996 Camaro RS, 3.8L coupe that has been idling very rough, and misfires when I drive it. My code reader gives me P0305 which is cylinder 5 misfire. I have changed spark plugs twice now, and plug wires with no results. What would be the next step in the process?
Do you

Check the injector pulse on the 5 injector and also check the resistance of the injectors. Also check to make sure you have spark at the plug wire.

Roger that, and how do I accomplish these tasks? Is it similar to doing a compression check? Also I took the plug wire running from the coil and placed a spark plug in there and I got a good arch. So the coil is firing off.

On injector pulse you can unplug the injector and with a test light go across the 2 wires(you will have to make a jumper to access the wires in the plug) if the light flashes when its running then you know we have injector pulse. If you have access to a ohm meter you can use that across the terminals of the injector to check resistance and all injectors should be the same. To do a balance test we need special tools to check if the injector is firing itself. Also first thing is to try spraying carb cleaner around the intake manifold to see if that will clear up the skip, this will tell us if there is a vacuum leak.

Well I parked the car yesterday, went into a store, came out, turned the key to the sound of silence. Just one tick, then nothing. The battery still has a charge.

Loose battery connection for sure. Remove cables from battery and inspect
