Yesterday I changed my oil and the small PCV hose that connects to the side of the intake boot (2L5E-6853-AB). Everything was fine for short errands I ran earlier and then all of the sudden I feel the RPMs suddenly drop while driving. I throw it into neutral and attempt to rev it up to keep the engine from shutting off. I am hearing a low gurgling sound the whole time. I manage to get home and open the hood to find the new PCV hose I just installed disconnected from the rubber elbow. I plug it back in hoping everything is fine. I would idle really low and rough.
These are the codes I'm receiving:
P0102, P2195, P2197, P0171, P0174, P0300, P0316. I'm no mechanic but based on what I changed today and the codes that are popping up, I have some sort of vacuum problem.
Now my truck won't sustain idle. It will rev when I turn the key and drop down to zero.
This morning changed the large PCV elbow that is known to give P0171 and P0174 codes. It had a big gash in it.
I noticed that this sensor wire has been ripped up, and I am wondering if this is the problem. I'm not sure what it is called.
Anyone have an idea what's going on?
