my '76 was running like s**t the other day, spitting out gobs of black smoke and
sputtering. it turns out the coolant temp sensor connector had so much corrosion on it,
the computer was reading infinite resistance thus causing such a very rich mixture. i
temporarily fixed it by unplugging and plugging the connecter several times.

does anybody know a good way to clean the corrosion off fi connectors? i've heard vinager
will work ??

Buy a new temp sensor harness! Call Mike McGinnis at Banzai Motors (301-937-5746) He has a subharness that connects the water temp sensor and thermotime switch to the EFI harness for about $30. Let me know if you call him and he still has them. I need to pick one up too. Good luck!

Ross,
Save yourself some time & money. Go to your local Nissan Dealer and get new pigtails that run from the sensor tot he wiring harness. I paid $7.50 for mine. Might as well replace the Thermotime switch lead at the same time.
Then go to your favorite local autoparts store and get a can of electrical contact cleaner if you want to try to clean the bullet connector at your wiring harness. Otherwise just go to the electrical section, buy some new connectors, cut your old ones off and replace them. That was what I did. I still bought the contact cleaner because every electrical connector in my car is starting to go bad. It's a '77 280Z.
Merry Christmas,
Phantom
