My 79 280ZX loses power

[Goldy]

Hi I am at a loss and a friend found this site for me. I have had 4 mechanics look at my car (79 280ZX) this last month and $800.00 later my car is in the same shape as I started. So, I thought maybe someone on here could assist me or they had the same issue?

The issue= I will be going along and the out of the blue her RPM and OIL gauge(needles) will drop and she wil die, BUT if I am going at the right RPM I can pop the clutch and keep going.

I never know when this is going to happen and so she sits and I hate it because I miss driving her. Can anyone help me?

Thank you

Check all your electrical connections. Somewhere in the system, the car thinks it is no longer running, and shuts down. Could be a bad connection at the AFM, or at the oil pressure sender, or anywhere else for that matter.

Don't just eyeball the connections. Disconnect, clean, and apply some dielectric grease.

Could also be crap in your fuel tank suffocating the system.

You say that several mechanics have looked at it. What did they do? Where did they look?

And this may be the most important question: Do you have a Factory Service Manual? Odds are that the mechanics you gave money to DON'T HAVE ONE, and were basically guessing...badly.

As Davi said, get the FSM from http://carfiche.com/manuals023/cars/, that´s from an 82, but is pretty much the same......, i would check the conections to and from the AFM (air flow meter)...
