jdm h22a v-tec problems

I have a '00 civic w/ a 92-96 JDM H22A. For a while my v-tec kicked in but when it would first start to kick in it would surge. Now it doesn't kick in at all. Whats up? can someone help me out?

may be its broken:eek7::confused::biggrin2:

check your oil pressure. if there isn't enough oil pressure, vtec won't engage. is the engine warmed up when you get on it? vtec won't engage on a cold engine either.
