I seem to have trouble getting my 75 280Z running good. It all seems that the air flow meter is the cause of my problems. It blows black exaust back fires through the intack and has a lack of power. The hard part is the problem comes and goes. The other problem is that from time to time it also likes to hot . this problem also comes and goes. the last problem is the brakes. The brakes are very hard to operate. I have replacced every componet but the master vac. is this the problem or is something else.

>As for the brake problem. I think you need to check your brake booster. It is mounted on the fire wall on the drivers side. It is a large black cylinder. These can develop a leak and lose their fluid.
As for the other problems, since they are intermittant, it is possible that the problem is a loose electrical connector.

I agree.. Clean all connectors with an electrical contact cleaner really good. Then if it doesn't work??????????? I can't answer on the brakes..
