1999 SD 250 V10
My truck keeps misfiring like crazy. Changed 3 coils after I bought it and ran alot better. Changed all 10 plugs with cheapies and ran even better for a couple weeks. Then I finally changed all 10 to Ford Motor Craft and could see a huge change. Even sounded different. Now 2 weeks later it is starting to misfire again. The remaining 7 boots are cracked and oily. Should I waste money on new boots or just start buying new coils every time I get a chance?

new boots are your best bet..
cheap and actualy could have been alot of the source of your troubles right from the start..
be sure to clean out the plug holes with compressed air (watch your eyes)....
