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....

well if your getting code 21 either the slenoid is bad or power to it or ecu,,if you have a oil pressure switch yes it needs to be wired up
 
first so what ur saying if i never had a vtec oil pressure switch i dont need one? and second vtec is workin i popped vtec once for like a second then it shot a code and no more vtec... and i took my workin vtec solenoid from my jdm engine to my new usdm one....
 
after you swaped selnoids did you pop it then and what ecu are you running, and it dont need a pressure switch if it didnt come with one
 
running a p28 chipped ecu, well it did pop for like a second one time and then again it threw a cel. but i dunno man i have no idea why it isnt popping vtec but then again after it throws a cel and i turn off the car and restart it it goes away until i try to pop vtec at 6 grand. is someting not grounded or what i really dont think the solenoid is fucked up.. im leading more towards the wiring...
 
yea thats what i think also wireing check all your grounds, and make sure the selnoid is good and clean like the screens, if all your wires are wright check to make sure you have enough oil in the motor well check that first, and also swap out ecu to see if thats it and after all that check to make sure your getting good oil pressure
