93 240sx dohc, bog and rough idle.

[TweakinT]

I just recently bought a 93 ka24de 240sx, it ran fine for maybe 2 weeks, 3 at most. then it started bogging at first it seemed to bog around 5-5,500 rpm, i dont drive it too much, now it bogs hitting the gas. it starts around 10mins after i start driving, if i just barley hit the gas just enough to speed up a hair i wont notice anything, as soon as i push pedal anymore it bogs, i can literally floor the gas and it will do nothing at all, it doesnt try to cut off either. besides this problem it was fine, now it sat for a weekend, and i got in it on monday and it was idling really rough, like the whole car is shaking rough. im not sure what the problem is. i have a few ideas but has anything went through this?
