Vacuum leak probably
I was planning on driving home for the holidays but I swapped the radiator and air filter and now lose all power at 55 with codes p0308 p0307 p0174 which tells me vacuum leak
I pulled the whole piece between the throttle and air filter out and fixed a leak on one of the big plastic lines going into it but I'm not seeing anything wrong otherwise except the air filter doesn't quite fit right and I'll be getting a new one today but any other ideas because I've cleared the codes repeatedly and they keep coming back

What is it that you're working on?
The air filter needs to fit correctly. The whole system is designed to give proper flow around the MAF sensor. Turbulence can cause MAF sesnsor problems. Put the old filter back in and see if the problems go away. Or unplug the sensor.
