Vacuum Leak

Had the codes read at autozone and it's throwing these:
P1111
P0171
P0174
P0133
P0153
One of the plastic bits that sticks off of the accordian hose is broken and is rigged to stay on right now. I can hear a small hiss coming from this area and I'm wondering if this might be causing the CEL to come on. I don't know enough about jags yet to know where my problems might be.
Also, what is the name of that accordian hose thing? My JTIS is in the mail and I'm having trouble looking up the specific part.
What are those little plastic things for anyways?

Hi Rick
Where is this hose located on the engine? Is it attached to the supercharger?
I think we need more information to be able to help you.
Here is an extract from JTIS about Air Induction System on your XJR:

Ah thanks! That makes it so much easier to explain.
It's the Intake Air Distribution and Filtering system.
One of the tuned stubs broke off and the previous owner simply reversed the tube, stuck it back into the hole, and JB welded it in place.
I hear a slight hiss coming from here and I know that if it's removed the engine itself stalls. However I can drive normally like this until I get my new air intake duct.
Can this be the cause of the codes I'm recieving or is that a whole seperate issue?

First of all please put your car info in your signature. I had to go to your profile to see we are talking about a 2000 xjr.
Any type of vacuum leak on this car will set a code. If you know that you have a leak and you know where it is you need to fix it. This car does not like vacuum leak and will set a code every time and if you think you can patch it with tape I can tell you first hand that band-aid will not hold up. Fix the leaks that you know of and see if your codes will clear.

Hi Rick
I looked the Air Pipe on the JEPC (Jaguar Electronic Parts Catalog).
Here is a jpeg file of the page (find your Vin# and get the associated part number):

This part should cost around $38 plus shipping -- if it is part# NNF3555AC (priced at jaguarmerriamparts.com).

Hah no worries on band aid fixes. I used to own a corvette and I'm all too familiar with "Bubba".
I'm going to replace it with genuine OEM parts. The Air Pipe is already on order and I'm going to buy a new duct seal for it too.
The worst thing I'd ever seen was someone splicing the radio into a throttle locking cruise control. Every time the radio was turned on it would cause the car to lock into whatever speed it was at and you couldn't disengage without turning the radio off.

I will try and be helpful, but it is hard not to sound like a wise ***- You have the car and have identified that it it the SC leaking. Where? How do you know? How are we supposed to know not looking at the car?
If you are asking for where around the SC leaks can form, I would look at the rubber seals where the SC outlet plenum connects to the intercoolers. There are two varieties of rrplacement - one for the AJ 26 and a different one for AJ27. Your's is the AJ 27, I BELIEVE.
Good luck.
