hey guys so heres my problem. any input is appreciated


so i was driving my car the other day and out of no where the car bogged out and didnt wanna go anywhere. it did this when i first got the car just maybe only once a month. now it does this as soon as the car reaches operating temperature and after driving around for say ten minutes. also when pulling up to a light going to neutral the rpms drop to around 200 then slowly climp back up to normal idle around 700. and today after driving and experiencing these problems i let the car sit in my driveway and idle and the rpms were droping to nearly 0 then jumping back up to normal idle speed.

i recently changed the spark plugs thinking that would fix the problem. but of course didnt do anything. also installed new fuel pump and yet again.... nothing.

when it does this the rpm's drop and hitting the throttle does nothing, then out of no where if u keep your foot on the gas it just loads n pulls out of no where

 

motor is stock b18c5 in my type r
