    I changed my spark plugs due to a cold-start rough running engine and just put up a video on YouTube for those of you who my be interested. Removing the engine compartment panels can be found on videos posted by others on YouTube. I made the video after researching and seeing some of the problems/ questions other had regarding this job .

    Uh oh. Ever cleaned your EGR cooler and intake manifold? How many miles on the car?

    How long of a socket extension did you use? I have a lockable 6" extension that I want to use, but I don't know if it is long enough.

    200K? You really need to bite the bullet and do the EGR / Intake manifold clean out.

    NutzAboutBolts has done it all:







    The EGR system is the weakest point on these cars. Ignore it and you'll have the fun of dumping the car or replacing the head gasket.

    Where did 200K come from?

    I think you're good, but it's been a while. To be sure, pick up an additional 3". The latter's a very useful length, you'll need it for other applications.

    If your spark plug socket has a rubber insert to grip the plug, tape the joints between extension(s) and socket. Particularly after torquing the new plug; there's a risk the socket will stay on the plug when you pull the extension out.
