I want to know where to hook up smoke machine? I tried hooking it up to the hose that comes off the brake booster and into the air inlet hose but the smoke just came out the port leading away from the air box? If someone could screenshot the picture and circle or point to the location I need to hook up smoke I would be grateful. It’s my wife’s car for work and I’m not gonna be around to fix these things much longer for her.

So this is a pic of where I hooked up smoke

This is a pic of where it all came out! Lol

 

I have tackled this code my self my issue was a failed fuel pressure sensor and clogged EGR this fixed my lean code also double check you intake hoses past the mass airflow sensor as a loose hose will cause this issue I would check there first before the sensors mine was a combo issue I would also suggest giving the throttle body a clean while your in this area the EGR feeds in right behind the butterfly flap so it gets pretty nasty back there
you will have codes associated with the sensors or EGR if u do then chances are its linked
