    The # 1 cylinder does not seem to fire, I can remove the plug wire and
    there is no change in idle. I have verified that the injector, plug
    and plug wire is working properly by swapping it out with another one.
    There seems to be lots of spark. No smoke at idle or when revved up.
    Could it be the cam or the timing belt? There were no other signs
    leading up to the rough idle, aside from this issue the car is in
    great shape.

    could be a burnt valve - do a compression test to diagnose.

    Did you also check the spark plug to verify it is good?
