    Replacing original plugs/wires 93 SDV........wish me luck!

    I know the back 4 plugs are going to be brutal. Here's to hoping the original plugs after 19 years and 100K miles cooperate on the way out.

    good luck!

    I plan on doing mine within next couple weeks.
    I've never even changed spark plugs, I just got the car last month, 202k miles on odometer so I dont know when they were last done.

    I also have '93 sdv, Please post anything special i need to know about this procedure!
    thanks
