I have a 1990 300zx NA been sitting all winter and spring is coming. What do all of you do as far as spring maint items?
I plan on the normal, chainging the oil, charging battery but what specific items do you do? Would like to hear some opinions so I can add appropriate items to my list. Thanks

Re: Spring Maintenance To Dos
How long was your winter?
My only rule of thumb for 3-6 months storage was to make sure fuel stabilizer was added before winter. Coming out of storage, I'll drop a fuel system cleaner from STP into the tank and run the car around town for an hour or two.
Changing the oil is a good thing, as well as the regular checks of tire pressure, other fluids, etc. I'm sure there are others with some good input as well - I will keep an eye on things here to see what comes up!

Re: Spring Maintenance To Dos
Your '90 will have old style injectors and connectors, and worst yet the injector circuit is "always on" due to the wiring at the time (unless you removed the battery) which creates electrolysis and worsens corrosion of the connectors, and ravages the injector. Carefully remove the connector looking for green gook, clean them well and use di-grease when replacing.
Other connectors also have the same issues- you power transistor unit connectors (two big connectors on front of engine) as well as the air idle control valve connectors. This can cause idle and driving issues if left uncleaned.
RicerX covered the fluids well except the radiator, be sure to check that and the overflow, and replacing your air filters and cleaning the MAF unit isn't a bad idea either.
I also like to use graphite key ease on the door locks to ensure no freezes or binds, and a good interior clean is a must as well!
I think that covers my own service pattern...
