i just got this honda and i had a problem with the idle going up and down and when taking off it will stumble and try to cut off but it you are light on the gas it drives fine. i found out about the fast idle valve problem and tightened that down and that took care of the idle but it still wants to cut off on take off. i did a tune up, checked timing and replaced the fuel filter. i have no clue where to start next.
