Rpm Dropping & Turning Off While Driving

[EVLr333]

Hi Guys,

My r33 GTST is doing this weird thing were it drops rpms while driving which causes the car to turn off ! Also the oil pressure is dropping abit its on the second bar ..

Ive already tried cleaning the AFM but still nothing.. It kind of all went down hill when i put in a intercooler.

Also the exhuast is letting out black smoke when i rev it and it spits out dirt kind of..

its running stock boost ..

check your pipes for leaks. search how to pressure test system.

Make sure you intercooler has no leaks or moisture in it or borrow an AFM off a Mate and swap to see if this solves your issue mine did similar was AFM. Even after cleaning had to be replaced
