i recently did a swap because i blew my last motor, took out my jdm b16A for a B16A2 (USDM). the swap went well but when im supposed to pop vtec at around 6'rpm... it doesnt pop and the check engine light goes on. the vtec solenoid is connected right, the green yellow wire to green white wire... but its throwin the code 21 when i try to hit vtec. would it matter that i used the same vtec solenoid that was on my jdm engine? and one other thing also my idle is alil fucked it revs from 1k to 1,5k when in neutral at a stop. do i need a vtec oil pressure switch wire? i been searching on these forums and i heard about this but i dont think i ever had one. thanx for ur help....
