[John Rogers]

If there is a single vacuum connection on the throttle body it should be hooked to the RETARD side of the distributor (closest to the cap) since it's function is to pull the advance down when coming off high RPMs. The disconnected throttle switch should only cause a flatting of the accelaration when pressing the gas, which will be overcomed in a short period and you'll accelarate as normal. As for other components, refer to the Troubleshooting FI Article here on the PP site to see how to check each FI part and for a good explanation of how they affect the starting and running of the car. Good luck.
