I took my 87 GN out for a drive last Sat. It was running great. I shut it off for a short while to drop some laundry at the cleaners. When I started up and drove off, it started missing really bad. I'm surprised I was able to get home. I had a similar problem once when the connectors for the tube running from the intercooler to the manifold intake came loose. I checked that and they were OK. I checked vacuum hoses and they appear to be OK. What would cause this sudden rough running? Will it help to hook up Turbo Link and check for trouble codes?

You could. However, this sounds like ignition. You may have a failure in one portion of the coil pack or module. Test appropriately. I would start with resistance on each of the three sections of the pack.
