Try replacing the coils if the plugs/wires don't work.
Just replaced them on my '02 V6 Camaro after the cat converter went bad, plugged up the exhaust, and made the heat under the hood much worse. You won't get a trouble code for bad coils, but you might get a misfire code. Make sure that the rest of your exhaust isn't plugged up. The coils are cheap on ebay, about $65.
