I have a similar problem but the missing occurs ONLY during the first start of the day and only for 3 or 4 seconds. Are these the early warning signals of check valve failure? I was planning on replacing the plugs/cap/rotor at the next oil change but I hadn't thought of fuel delivery as my problem...
