Thank you for the reply.VRIS is all based on vacuum lines and the two solenoids on the intake. if you've got issues with then, you need to replace the one way check vavles, go to a fish store and get them there. And replace the vac lines, problem solved.
Not completely true, the valve can still fail when holding too much vacuum. look at the vris vac lines. my other point to is to change the lines. These are the easies means to finding out where your VRIS is failing. He's down to the last two things, check valve or vac lines.But he states VRIS #1 is now working, so that means the vacuum line is working. They operate off the same vacuum line. I don't see a need to take off the intake manifold just to check the stored vacuum plastic .
