Okay, I just boughat my first Z earlier today. My father owned the same 79 280zx model back when I was a kid and Damn it was awesome. I want to rebuild what he had and restore this one to its full potential but I just can't catch a glimpse of that happening. I've been battling with it since I got it home (I drove it 40 some miles with no more than some minor bumping in the front left tin rod and high revs in neutral and between shifts). I go to inspect my prize and I see chaos. The tube behind the mass air flow module (or what I believe to be) had been wrapped several times with electrical tape. Turns out it had a massive tear. Then I got it going again to test the high revs and it started going up and down between 2 and 3k rpms like it was galloping. Soon after it stalled. I was told it had a leaky exhaust manifold seal but this was not something I know to become of that. I started it back up and it launched the alternator belt clean off. I put it back on after turning the car off and it hasn't stayet running since. I tried puting it on both pulleys coming from the block but neither seems to make a difference. It'll run for five or six minutes and die a slow startling jumpy death. What all am I dealing with here!?!? Have I just thrown 2 grand away??
