      Replace the coil packs - this is most likely causing the misfiring. Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the coil from around $35.00 each for your vehicle.

      Sounds like you may have an injector or two that are not closing completely.
      Thus the stalling and the knocking sound when trying to start.

    I have a 2004 XJ8 and recently the fan continually runs even though the engine temp gauge never goes above the halfway p
    Noticed water under the car but the coolant level looks fine.

      Sounds like the cooling fan temperature control switch on the side of the radiator- or on the engine block is faulty. Try pulling a wire off of a visible temp switch. If the fan stops, that will be the switch you need to replace.

      Check the various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, www.radiatorparts.com, to list only a few.

      Sounds like the temp switch is getting tired. try pulling a wire off of a visable temp switch. If the fan stops, that will be the switch you need to replace!
