My jdm B16a all of a sudden just started not making power when I was driving home. There was no weird noise or anything. It feels like there is a loose plug wire or something, but ther isn't. It almost feels like it is running on three cyl. Please let me know what you think it could be. Thanx alot.

 

does it still go into vtec? Are you low on oil. Is there anything blocking your air filter or exhaust flow. Are your plugs old.
