Did you disconnect the timing wire before you attempted to set the timing? It should be under a cover on the firewall. A tan wire connector I think. You have to disconnect it while using your timing light and adjusting the distributor. Disconnecting it takes the pcm out of the equation, so that it isn't trying to compensate for your timing procedure.

Is it possible that you didn't get the wires back on the correct plugs? Happened to me once.
