ok kewl. but i still dont know why it misses as if it is running on 2 or 3 cylinders when it is cold (below 20 degrees C). if it warmer than that it runs fine. do you think it could be the leads??? is there a book available on it that i could read to see what it could be?? the mechanic at honda says there are little filters in the vac lines that could block up and cause this.
