Question
I just replaced my spark plugs and now have a cylinder 4 misfire. changed plug and wire on number 4 still nothing?

Answer
It is possible that Plug Wires are running too close to each other, and you are experiencing current bleed from one Plug Wire to the other. Also, if your car still uses a Distributor, a bad Cap would be a possibility. The only other thing to check for, is a bad Valve, which would require either a 'Leak Down' test, or a bad Valve may be found via using a Compression Tester.
