So my girl just picked up a 91 300zxhttp://images.intellitxt.com/ast/adTypes/mag-glass_10x10.gif (http://zilvia.net/f/#) na car 1 owner the guy only drove it like 800 miles a year for the past 3 years or so.......supposedly new plugs injectors all those little things.

So let's say when the weather is nice outside and sunny the car everynow and then but not all the time will hesitate up untill about 3k rpm's and then it act's fine but when it rain's or very humid and alot of moisture in the air the car hesitate's all the time to the point where u feel like you need to pull over and park the damn thing.........I was thinking maf sensor but i really want to ask around first for other possibilities because i really don't know the engine's for shit.

The car also has a little miss to it at idle. any help would be appreiciated and yes i did search but didn't find anything about being humid outside.

clean out your MAF with brake cleaner let it air dry. try to turn it over if it doesnt then redo the ground or start to troubleshoot for other possible problems. Maybe effed up fuel pump or your TPS is jacked up. good luck...

wiggle your whole engine harness too before you do this while having someone crank it over

not brake cleaner but MAF cleaner. Do not use brake cleaner unless you want to buy a new MAF.
