Need some help guys!

Basically my bike started to run poorly and kicked out a c 25 code, turns out the coil was bad. Changed that and no f1 light but when i let her warm up the throttle response is poor but when i turn her off and then back on shes perfect. Would a bad plug cause this and could a bad coil foul plugsve got less than 100 miles on my plugs. ANY help would be great fellas! Thank you
 
It doesn’t sound like a spark plug to me..if a plug is bad its always bad not okay after you turn the bike off and back on again. You could clean them....that never hurts. A C25 code has to do with that entire coil circuit...Have you checked all of the electrical connections in that circuit and is the battery good? A poor battery ground will cause all kinds of weird electrical issues.
