Checked mine recently, seemed like it was on there pretty tight. I think I'll zip tie it anyway.

 

Mine was detached! Fixing this did correct my rough idle issue. Thanks!

 

Zip ties fix everything!

 

Sorry to revive an old thread, but I wanted to say THANKS!!!!!!!! This hose had come loose. I had the same issue with my idle fluctuation wildly and had taken it to the dealer once. Even though I asked, they were not interested in pointing out what hose had come loose, but they had "fixed" it under warranty. Happened again, obviously and I took a different path looking here for answers.

Turns out this can really confuse people I think. I had also read about doing a proper reset / clearing codes etc - of which I didn't find any but my service engine soon light was on. Anyway, I flashed it with my AP - and cleared learned memory. What I forgot to do was let it idle for some time after starting it up. It didn't idle strange at first, but when I turned on the AC it started fluctuating again, almost like before but not as crazy. I took it for a spin, hitting WOT pulls to 65 ish a few times and it's all normal now. If idle goes nuts again, I'll check the hose - and if it's still connected, then I'll clear codes/ learned memory and do the proper procedure.

 

Mine never blew off but it seemed stupid not to put a $0.20 zip tie on just in case VS a blown motor!

 

+1 +1 +1 !!!!
Thanks - my car started idling rough this week - the temps started dropping into the 50's so I thought that maybe it was due to cooler temps or a bad tank of gas.

But nope - this hose was off mine too.

THANKS!

 

Lol I used a zip tie and a little bit of epoxy around the base of the nipple. It won't come off without a fight now

 

knock on wood*..mine never came off 2010 gsr w/ 30k and i still dont have a zip tie on it :P but i will put one on today just incase

 

Mine came off and I did a silicon hose replacement.

This is how it looked like :

 

Just to be clear, since it isn't in that picture: there needs to be a zip at both ends.

 

Thanks.
It's in both ends, just that in that picture, the bottom end is not seen clearly.

Anyway,
Using Silicon hose, it is not as easy to slip out comparing to the stock hose. Cable tie definately secured it tightly.

 

Where is this located??

 

On the intake plenum.

Open hood. Stand in center in front of the car. Take a step to your left. Look down.

 

Thanks, my idle would sometimes be a little weird so when I checked it the hose was on tight and ok...I guess the Evo X has some idling issues sometimes?

 

very helpful with pics, thanks again
