Was attempting to change the spark plugs on my 2009 Honda accord, got all the tools, equipment, reviewed videos and forums, got the cover off with some wd-40 at the bolts, however all 4 bolts for the ignition coils are not budging. Tried spraying wd-40 on them twice, waiting 30 minutes, tapping top gently with hammer prior to repeat attempts. still not moving. What would be the best solution to getting the guys unstuck.
