did it do it out of nowhere or did you work on it and then it happened?
ive seen reverse wired injectors do very similar symptoms before when wired 4/3/2/1 instead of 1/2/3/4
you need to get a multimeter and the specs for all the sensor ranges and start probing.

it definetly doesnt have anything to do with the oil level or vtec sensor though. thats obviously coming from someone who doesnt work on hondas. the vtec oil pressure switch is what he is trying to speak of not the solenoid and even still, if you have low oil, you can rev the hell out of the car, vtec just wont work because of lack of oil pressure.
