I was wondering if any of you have had this code? What was it? Was it a coil pack? Or the pvc hose? O2 sensor? Please hello!

It's usually a vacuum leak. I would check the pvc hose, or the pvc itself.

I checked the pcv hose and it looks like its still good. The engine is stumbling. Cou,d any of that cause the engine to stumble?

Even the 90* elbow on the back of the intake?

I checked it and it looked fine. It stumbles like a bad coil pack. But I dont think its a CoP would an o2 sensor cause it to stumble like that?

However the hose coming out if the top rear of the throttle body leading to a module mountedon the fire wall infront of the drivef; that hose is starting to crumble. But I dont think thats part of the P0174 code?

For me it was that one of the hoses came undone randomly. I reconnected it and it never happened again.

So I found out what was causing my error... a spark plug with carona. It's all fixed. I eventually got a misfire on cylinder 7 so from there I found the spark plug faulty
