Just changed sparkplugs from who knows when. I installed Autolite Iridium and now it mis-fires, Why? Please Help Our Family This Holiday Season. Need our car to go to the Mission for Christmas.

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.

Roy: Sorry I keep answering the ones you already got. It shows that they still need answered when I do it. Sorry. Have a nice Christmas.
