Run a compression test, especially on the cylinder that is misfiring. If the compression is up, it's either the ignition or if the vehicle is manifold injected it could be the #5 injector. If you suspect ignition, try the plug, distributor cap or the wires. Can I run a compression check myself? If so how? If not would it be in my best interest to just replace the plug wires cap and rotor first? About the brake question, I meant brake switch not relay, brake lights are not working, not bulbs not fuse what else could it be? Look at the switch at the bottom of your brake pedal. It might have come loose or has shorted out.
