Also, when in neutral or sitting in first gear with the clutch depressed, the car likes to actually rev itself without me giving any throttle. It'll fluctuate from about 500rpms to 1000 rpms, occasionally jumping all the way to 1200. This is when I'm just standing still at a stop light. It's so pronounced that a 350z actually thought I was trying to antagonize a race one time... Lol. I do know that I need a new o2 sensor but not sure if that even would cause something like this. Any thoughts or is it just a 16 year old car acting weird in the humidity?
Most likely suspects; MAF failing, throttle body dirty, or intake/vacuum leak.

Nothing to do with humidity.
