    Multiple misfire on cylinder 2. Start with plugs and wires.

    MSD Ignition is a waste of money...also...assuming your car is stock you want stock heat range and OEM replacement plugs...example...Autolite 606's are great plugs. Also...if your wanting performance oriented...buy some PRJ Performance 10.4mm spark plug wires...pricey but you never have to buy another set again...

    You only need colder plugs if you will increase boost, otherwise colder plugs will not get hot enough to clean themselves

    I'm going to use tr-55's in the next few weeks as the irridiums did not last nearly as long as they suggested they would (i'm running a 3.5" pulley on a 98 gtp)
