I am throwing this code. I have done some research on it, and havnt really seen much about it being closed. It doesnt really run bad. So what should I do?

I tried to do some research for you. I have a single port so I know very little. from what I found, it looks like you need to clean your IMRC. It gets gummed up just like the upper intake manifold that we all have to deal with using Seafoam treatments. There appears to be linkage just like a throttle body and a controller to open and close them.
That's all I could decipher. I would think that that indicates a serious Seafoam treatment is needed no matter what.
I'll check back to see how you fix it. Good luck with it. Sorry I wasn't more help.

you could also do a IMRC delete, but that depends on how comfortable you are taking apart the intake.

i agree with this, seafoam does wonders. put half a can through your pcv line and itll probably cure it. search about seafoaming of you dont know what it is.

I got a bottle of seafoam. Im goin to do it in a few minutes, Would it work to put it in the vaccum hose that plugs into the Air intake hose and goes straight to the itake manifold?

Since it's before the TB, I don't think there will be enough vacuum to get it sucked up easily. Just use the PCV line that runs between the upper intake and valve cover on the drivers side. Pop the end out of the valve cover while the engine is running and let the hose slowly suck up the Seafoam (don't just dunk it in or the engine will stall).

Well, it made a little smoke, but I didnt add enough seafoam. But it does seem to idle better. I am goin to repeat process tomorrow, but I will use the right ammount.

how much did you pour through? i would use at least half a can if not a whole one. probably just put the rest of the can through it the next time you do it.

+1. I use at least 1/3 of a can in the upper intake just for a basic cleaning.

I dont see why it would!! It was originally meant to be a fuel treatment/injector cleaner. You can use the hose in front of the tb. Just remember it'll be a slower process but it does hit each runner better. The more RPM you use though will also lower the amount of vacuum which is what McQ is talking about i believe.

i just used the other end of the vaccum hose to pour it in, it honestly took about a whole 5 secs for me to get half a can in there. it should be plenty of vaccum
