I came across this tech article and it says it applies to 280Z and ZX, thought some of you might find this of use.

That is a good article on checking the L-Jetronic. The instruction works on all the L-Jetronic cars, lk BMW 5 series, Mercedes, Volvo, Citroen, Peugeot, Alfa Romeo and Datsun. For some reason Datsun was very late the include a O2 sensor.

I was thinking of going with a BMW 5 series ECU to get the O2 sensor. They are a little easier to find parts for, over here.

He did have another one where he suggested adjusting the afm spring for "performance" which is not really true. Adjusting the afm only compensates for other problems.

Great article, especially the photos. Thanks for sharing.
