Engine misfire on 2011

I have a 2011 and its been running fine. Today fired it up and it sounds like a misfire to me.

I tried new spark plugs, nothing. Found a coil that might be bad, replaced it, nothing.

The check engine light comes on, and it says engine power reduced. It'll go into reverse, back up, and go into drive, but if you give it any gas it won't take it.

I took a short video. It's hard to tell from it the kind of sound its making. Its not a continuous rattle.

It kind of goes "put put put vroooom" and then back around. Keeps doing that cycle.

Any advice is very much appreciated.

CEL is on there must be stored codes... Have those read and post the codes here. (Just the code, not what somebody tells you what they mean) Most auto parts stores will read the codes for free, and tell you a bunch of "stuff" about what they mean, (often wrong, they want to sell you parts) as I said all we want is the code.

Thank you for the reply. I don't live near a major auto parts store, but there is a couple shops nearby that might can do it free or cheap.

I plan on doing that first thing in the morning, I was just wondering if anyone had a general idea as to what I might be in for.

Codes please.
How old is the battery, original?
A dying battery could cause this and a dirty throttle body, broken flexpipe, unplugged MAF, enough guessing.
We need the codes.

Battery was replaced 2 years ago. I bought the expensive 5 year one because of how big of a pain it was to change. Why put a battery in the back if the back latch won't open when the battery is dead? I digress..

There are at least 3 ways to open the tailgate with a dead battery. One is in your Owner Manual, 2 others become obvious when you stop and think that it only takes 9 volts.

The question should be: what is the condition of the battery not how old is it.

The CEL does not speak.

I do note that the aircleaner is not installed in the video, a disconnected MAF will cause the symptoms. Did it do this when the aircleaner was installed and the MAF connected?

And a huge hole in the PCV hose, that is a vacuum leak.

Update: I took the fuel injectors out, cleaned them out, put them back in and now it fires up fine. Still has a check engine light, if that doesn't reset I'll take the 30 minute drive for a free test.

Did you hook the MAF up, did you address the PCV hose?

Just wasting my time?

Sorry if I said something wrong I'm not trying to waste anyone's time. I don't know what a maf or pcv are. Yes the air filter holder was disconnected purposely to get to it. It still did this with it on.
