1981 non-Turbo gas: I posted about three weeks ago about how my car started running really badly and died right after a gas station guy really overfilled the tank. I learned about the evaporative emission system in the process of tracking down the problem, but as it turned out, the problem apparently had nothing at all to do with the overfill. The timing of the symptoms was just a coincidence. I found that the plug to the ignition controller was a little loose. I'm guessing that as the connection warmed up, one or more of the connecting points became weak which caused the car to sputter and die. Cleaning the connecting points and putting the plug on tightly seems to have fixed the problem. I've run through the whole tank of gas to give it a good test. Thanks for all the advice.
