i have a problem with my car that i have no idea what it is doing. right now, it is ok but it seems that from 4 1/2 -5 1/2 rpm, power is just not there at all. i know that a vris point is around there and i can certainly hear it opening, but it seems like it innit doin anything. i read about the paper test and all, but where is the vris solenoids located at? any help would be appreciated since ive written about these problems befroe and nobody replys. thanks.
