I just purchased a 1977 280Z as a project for my son and I. We are new to the Z car world. The car runs pretty well considering it has been sitting for a few years and is drivable after getting a new set of tires. The car is stock with the exception of triple webers and some modification to the vacuum advance that I don't understand. We are in the process of putting together the priority list for this project which will probably take a few years. But, in the meantime I would like to make the car a bit more drivable. The immediate performance problem is that the engine "bogs" down when accelerating in 1st and second gear. The car doesn't stall out completely but seems to be starving for fuel. To compensate, you have to start out with at high rpms. The power loss is dangerous when pulling into traffic and especially dangerous for my son who is just learning how to drive a manual (so no, he is not driving the car alone or on a daily basis right now). Once you get the RPMs up, the car runs great. The car idles fine also. I know there are probably a 1000 things that could be contributing to this problem but I thought is would be worth a shot to get some initial feedback from those with some experience. My gut says that whatever was done to the distributor to modify or shut off the vacuum advance is the issue. Thanks in advance for your input!
