    4.5 Miss under full throttle

    Hello,

    The Seville has a miss under wide open throttle. Any ideas where to start? The plugs and wires aren't the originals. Thanks

    Generally, a miss under full load can be traced back to plugs, wires, cap, or rotor. Do you have an idea of the age/mileage on these components?

    I'm not sure how old they are. My next step is to go through these items. Thanks!

    Also make sure your plugs and wires are AC Delco. There have been many reports of missing when using other lower cost brands.
