Thanks, I think I will go the now Opti route when the sun finally decides to show itself again around here.

I like to try and wrap up my post so here goes. I got the new opti installed and swapped out the check valve on the hose that comes out of the opti and goes to the intake. There were 2 on there that seemed to be working against themselves I looked in the FSM and didn't see anywhere where it talked about 2 of them so I just put a new one on. When I got it all back together the car was running much better but I still have my wandering miss or stumble that I am working to fix. I checked the vacuum on the hose that comes up to the intake and I have 20 in hg on it of manifold pressure.
I think what happened was that when the opti was swapped the first time by the previous owner they might have installed the check valves wrong but the hose was worn out below the check valve so it didn't cause the opti to implode. When I swapped the opti out I could see the hose was bad so I put new hose on and installed the check valves in the same way they came off thus causing the opti to implode under internal pressure. Funny it took it so long, so lessoned learned.
Now to find the miss or stumble problem and I will be happy.
