Inconsistent idling problem

and this from a post on warm idle issues...

WOW! What a difference that made...totally fixed the spark issue! Thank you. Cold, the coil is testing at 9.6v...a lot different than the 6.2 it had when the ballast was in place. Cold startup is much easier now, too. Once warm, the spoil is staying at the same voltage, so there's no more miss. Win!
