I have a 2000 civic dx with b18c1 swap. As im driving through 1-3 gear my handbrake light will come on at about 2500-3000 rpms until i shift, then it will go off and come back on at about the same amount of rpms. Also when i get on it a little bit and it hits vtec it doesnt really want to go and theres a noticable power loss from the time ive got this. Ive been told its the vtec solinoid but i really wasnt sure. So i am just curious of what you guys think it would be. Its also throwing no codes when i check it.
