Once you start having to replace coil packs, its usually prudent to replace all of them. At 250K miles, your in a period of the cars life where a lot of parts will be waring out. Have you replaced the alternator yet? Also, the cooling fan motor will need to be replaced soon if it hasn't been. But, the good news is that after you get through this period, you can expect many more miles of maintenance free driving. I know fellow limo guys who drive their car well into 500K miles. Good luck.
