I am the new owner of a 78 280z....ok..ok it's a 2+2, but I had to get back into a Zcar. It's not perfect but it's got a solid frame and rails - which is rare in Missouri. My problem is that the accelerator sticks. I am able to pull the pedal back and it's fine. I have lubed everything but I think it might be the spring at the end of the rod (i think it's actually called something else). I haven't picked up a book on it yet, but I thought I would check with the experts first.
