Get the code for us. You may have a bad coil or a connection.

Did you check the gap on the plugs?

Did you gap the plugs? Are you sure you didn't get the electrode dirty or bump it when installing the plugs? If there is a misfire. The computer should pick up on it setting the check engine light. Then you can scan the computer to see what cylinder is missing. Then remove that plug and check it.
