hi i have a 2002 frontier 2.4l manual tranny and when i first start it up in the morning it starts to shake like crazy while idling super rough and sometimes die until it warms up. it seems like i have more problems on humid or rainy days. Recently it started to idle roughly when i am at a stop. have taken it to the shop repeatedly and they always say its o2 sensor, well its not lmao. any help is appreciated.

Check you plug wires, you might have corrosion at either end!

Any check eng lite? Check your cap -wires etc, start it up when dark and see if you can find any sparks jumping to ground from a defective plug wire. Be sure to use Genuine Nissan replacement parts!!!!
