I just recently got my 78 280z running after taking everything off the intake. the first owner had left it sitting for years. The car runs great now but it will sometimes die while I am driving it. I found out that if I tighten the living crap out of my AFM it will run close to how it did before. And I will be able to drive it with no problems until it will randomly change back to needing less air.
Its getting really annoying
If anyone knows what it is dong it would be greatly appreciated.
Things I've done: removed egr valve, removed cold start valve, removed air regulator, new plugs/plug wires, fuel injectors from an 82
