hi...i have a 2001 fd3s...i recently installed an Okada Plasma Ignition Booster in my car with the stock coils...the car started breaking up at 5000rpm...i then uninstalled the ignition booster but it still happens!...did i damage the coils?...is that possible?...the only other thing i did to the car in that short space of time was adjust the TPS but that was it...

i changed the plugs but it still happens...

can it be something else? i appreciate any help i can get...thanks
