  1. Turns out it's a relay for the defroster grid on the back windshield.
  2. Hello everyone. I've tried doing a search, but couldn't get anything. My 75 280z idles at about 1300rpms with constant misfiring throwing it up or down 200rpms. Not sure if those two are related. My concern here is the high idle though for the moment. All vacuum lines are less than a month old. My A/C & heat was removed by PO due to "electrical issues. Blowing fuses." My temperature switch (heard this could be an issue) does not function properly. When I connect it, she idles really high then dies. My AFM is new and was tampered with by PO, but I have it set at the optimal setting I think. Idle adjustment screw on throttle body is all the way down. Side note (note sure of its relevance): there is plenty vacuum coming off the intake manifold line going to the CC, but the small hose with the "T" in it coming out has ZERO vacuum. The throttle linkage is not sticking. Please oh please let your far reaching knowledge rain down upon me. Thank you in advance:)
  3. Here's a link to what I believe the culprit to be. (I hope that link works.) http://www.zcarsource.com/fuel-injection-dropping-resistor-280z-280zx-75-83-used_8_56767_65326.html
  4. Hello, I am new to the forums. Never been one for using forums, but I finally had to join since no info for this came up after vigorous searching. I have this relay or resistor that clicks very sparatically even when the car is off. It eventually drains my batter if not started for a few weeks. It's in the passenger footwell. Waayyy up at the very top of all that mess. I can see the numbers "504," imprinted on it. Anybody ever had to deal with this guy or knows exactly what this does? And furthermore, should I be worried? Btw, my z (1975) is running rough. Idles @1300 and jumps 200 rpm's in both directions. Really hoping this relay has somthing to do with it. Thank you ahead of time:)
