umm my friend has a b20vtec. it has a b16 head and ctr cams. the car was working perfect like about 2 weeks ago. but all of sudden his idle gets messed up to the point where he starts it and gives it alittle gas and the motor just stalls out. that problem we fixed some what. but now the vtec isnt working. sometimes it;ll turn on when it wants. but today it didnt wanna even go on at all, and we waited to rip it when the car was fully warmed up. i know the motor has enough oil cuz i checked and its full, and i mean full!! i checked the wiring between the vafc and the ecu and that seems to be good. just like it was 2 weeks ago.
so can anyone gimme any ideas or any thing to check for me to solve this problem..
im hoping it isnt anything big. thanks alot for your help guys!!!

 

Throwing any CEL's?

 

idk we didnt check yet. could it be a fuse or it doesnt run on them??
