Hey all, I just took off my UIM to inspect the vacuum hoses, since I located a vacuum hose that was completely off the nipple with the UIM still intact.

I plugged that hose back in, but in the process of taking off the UIM, I must have pulled off another hose.

Normally I'd just plug it back in, but on the end of this hose, there's this hardened piece lodged into it.

Here's a picture to show what I'm talking about.




Looking at the vacuum hose diagram, I think this is the vacuum hose connection to the double throttle control solenoid valve? I'm pretty much stumped.

 

you broke a nipple off a solenoid.

 

you need to be careful , and pull those 3 hoses from the uim wit the 3 check valves

if by any good luck miracle it was the double throttle body control solenoid , then you can plug it , and just eliminate it

 

you broke it

 

take a drill bit and start taking it out be sure to take off the other end and then blow through it or use a small mechanic pick to pray it out

 

What the heck for? Just replace the line as he'll need to replace/repair the broken solenoid anyway.

 

Thanks guys for the info. Guess I'll take it into a shop for them to replace all vacuum hoses and to fix the solenoid. Is the car drive-able in this situation?

 

you will more then likely have a boost leak , once the solenoid opens , so keep it out of boost if you're really **** about it . but Unless we know what solenoid went cant really say . with 100% security

 

I did that once too. I broke the barb off one of the solenoids that sit right down underneath the nest, under the row of solenoids along the top rail. I replaced the solenoid without taking anything else out. It took 2 hours and a lot of swearing :p

There are (from memory) 2 different types of solenoid. Make sure you replace the damaged one with the same type/part number. Good luck

 

found out it was the double throttle control solenoid.

 

You will have a vacuum leak...and probably a high idle, but it shouldn't do any harm short term.

Since you're replacing those hardened vacuum hoses, I recommend PM'ing a member named DaleClark for a set of his check valves and replace those OEM ones at the same time. IIRC he also sells them through Ebay. A search with terms like "Viton" and "RX7" should find it.

 

Time to go single turbo and get rid of all of that unreliable parts.

 

just pull the check valve out and put a small screw in the vacuum line connected to UIM
that will stop vacuum leak and you can drive it normal - until you get replacement parts

 

Will do that until I replace the broken solenoid. Thanks!

 

Many broken solenoids can be fixed. Proper size brass tube, electric drill bit, metal saw, and epoxy glue. I have fixed many using the above materials.

If you can not figure out how to do it with this info, then you do not have the knack.

 

Hell I didn't even know I broke a solenoid, hence the creation of this thread. Needless to say I do not have "the knack".
