Idle question

Does any one here know how to adjust idle on my 93 nissan 240sx it is really low i know it should be around 700rpm but mine is 500 and below and it constontly tryes to stall becouse of that. And also might as well find out about this. When i press gas my car bogs down or doesnt wont to pick up rpm properly and low on power but once it crosses sertain point I can feel power come back to the engine and it accelerates fine but when i stop its same thing all over gain engine bogs down usualy betwen 2000-3000RPM I also belive it's somehow related to idle problem couse it started at excatly same time.

idk how you adjust or even if you can adjust the idle manually. I would clean your MAFS, and check for a vacuum leak. if those dont work, then i would check into the idle adjustment (assuming there is one) and then if that fails then i would get assistance or check for a leak somewhere with something. Has it always been doing this?

learn to heel toe when you come to a stop

Thx for all the help guys half of the staff i was in procces of doing other half is new and i will try that. Also i'm lerning how to heel and toe and geting beter at it :)

I have already cleaned best as i can the throtle plate and found bunch of black oily staff i dont even know what it was but it looked bad i cleaned it of as mch as i can so will see if it helps the idle problem.

the black stuff is most likely oil from the valve cover, theres a hose that connects to the intake (right near the tb) from the valve cover
