i put a cam in my d16a6 and well is the valve last suppose to be lower number on intake or exhaust side.. The valve lash that is . and ..what vac should my Vac gauge read at idle.. when i put the timing where i think it should be... it has -10 vac.. when i do the timing where all the marks line up . then i get 20 vac.. put i cant drive it just rev it.. and it revs some what fine..

I have a vafc.. when i lower the numbers at all.. it just starts running like ****.. like i cant rev it or anything.. it just pops and bogs and stuff..?.. what are all the COULD BE'S..?
