The 5 Way Tee

I'm sorry, wrong thread.....four friends and me sitting around having a spot of tea!! :biggrin: Russ.
 
Upon starting my 2007 last week, the initial idle was definitely lower than normal and uneven. I began receiving an FI Code 2 almost immediately. After some research on the forum, I followed all the great info and removed the 5 Way Tee, the old vacuum hoses, and the MAP Sensor. I cleaned the sensor with some Mass Air Flow Sensor cleaner, cleaned the tee with a pipe cleaner and carb cleaner (only a little crud came out), and then reinstalled with new MasterPro 5/32 hoses from O'Reilly's like the ones pictured above, cutting them slightly longer than the originals to elevate the tee some like suggested. I was a little concerned that the new hoses did not fit very snuggly onto the tee, but the tension from the opposing side hoses seemed to hold everything together alright. After reassembling everything and cranking the motor, the FI light code did not come on, but the idle was still pretty low. When using the throttle to raise the idle speed, I am getting a pulsing of the RPM level up and down. I've thought I might need to increase the idle adjustment, but I'm wondering if those not-so-snug vacuum hoses on the 5 way tee might have anything to do with this. I remember reading something about a similar idle pulsing issue somewhere on the forum, but I can't find that info again. Thanks in advance for any guidance and help!
Problem solved and my ST is purring as usual again! Larry @Igofar came to my rescue and helped me trouble shot what was going on over the phone. Thanks, Larry!!! It ended up being the too loose fitting Master Pro 5/32" vacuum tubing like what is shown in Post #11 above that I bought at O'Reilly's. It may have just been a fluke thing, but it definitely wasn't the same as the Prestone packaging from AutoZone.
 
It is 5/32" vacuum hose / windshield washer tubing. WV0532 is a generic part number. It is sold under many different names, not just Prestone, all packaged in the same blister pack and the same length. You should be able to find it an auto parts, or have it ordered. Or just buy any good quality 5/32" vacuum hose.

I bought this one today and found the fit to be loose on the 5-way! I can spin the hose freely and it may actually fall off on it's own. :(

I'm surprised as this has been used by many with no issues reported that I can remember.

Wrong size hose in the package?
 
No this is the package and brand several folks have brought me to install, and each time, the ID was too large, and it would spin and fall off!
I would NOT recommend this brand unless you want to do the whole job over again.
If I remember correctly, I got a call on the white courtesy phone from Aniwack, and he found the same problem with the same product.
So no, I don’t think it was a fluke.

I guess I got lucky.
I'll delete this one from my earlier post.
Do you know of any troubles with the Prestone version?
 
This is wrong ID. It has to be 3,5mm not 4mm (5/32")
The Prestone version actually measures closer to 3.5 than any of the others, and is a better quality hose in my experience so far.
