Look on the side of the throttle body, there should be a hose that goes from there to the PVC valve. I think I pulled that hose off and put on my own hose. What you should do is:
1. start the car first, find a little wedge and wedge it between the set screw that is used to adjust the butterfly valve (how far open it will stay when you are off the throttle). Wedge the piece of wood in so the idle is high enough so the car doesn't die too quick when the sea faom is sucked in.
2. After finding the right amount to wedge the wood in, stop the car, disconnect the pcv hose from the throttle body, put your own hose on (a good length), have your cup of sea foam ready and your thumb over the hose so the car will not die from running lean, have a friend start the car and make sure the wedge is in palce to hold the idle high, and when you're ready - take your thumb off the hose and quickly jam it in the cup of sea foam. Once all the sea faom is gone and if the car is still stumbling I would pull the wedge out or just have your friend turn the ignition off.
Clean up the mess, reconnect the hose and wait. then fire the baby up and smoke out the neighborhood.
