My 2005 Mustang running a little rough at idle, not too terribly though. I decided to check the spark plugs since it had 65,000 miles on it. The plugs looked like they needed to be changed so I went ahead and changed them. After this I drove the car a day or two and the car ran much better but every once in while it sounded like it had a slight miss. I changed the wires thinking they might need replaced too. The wires also helped and the car runs much more smoothly now but there is still the slight miss so I went back and checked my work. I checke the plugs and notice the middle one on the drivers side was only about half way in. I took it out, looked at it, and put it back in. It won't go in farther than halfway. Are the threads stripped? If so how do I go about fixing this?

Click on the 2005-2010 section, then click on the 4.0 section and post there this section is the 94-04 3.8 v6 section for future reference.

Take the plug out and check the threads. If they happen to be stripped replace the plug.

Did you try switching it with one of the other plugs to see if you still had a porblem and it was just the plug?
